Is hubby cheating

Oh dear; he has retired very early so is probably bored. You're out at work so that will contribute even more to his boredom. He's presumably only in his fifties but has chosen to sleep in the spare room.
It sounds as if you have lost communication between you apart from you telling him off about the porn and checking on his computer - it doesn't sound like a good relationship at all.

Can you start to pay him more attention, go out together, have some fun? Perhaps you may be able to find what you seem to have lost.

I wouldn't start accusing him of bringing another woman into your home without further proof, but, if he has, it could mean that this is the end of your rather sterile marriage and you may be better off separating.

I hope that doesn't sound harsh and hope that you can, in fact, retrieve something from your relationship.

How's it going with the sheep, the viagra and the porn?
Oldbatty; That's David's specialty;
My analysis of the evidence confirms my earlier diagnosis that the gentleman in question must be gay; with no further sightings he must have returned to the closet!

I think your instincts could be right and he is having an affair.
I know of another situation where someone, given the opportunity of an empty house during the day, brought a married colleague back for sex. I can't remember how it was discovered but it almost broke the marriage and possibly both marriages..

Oldbatty. Vix came on this site looking for help and support. Could you please try and be a little bit more sensitive ?

How's it going with the sheep, the viagra and the porn?

You would not confuse horse hair with human hair and black sheep are all wooly, men are not as observant when to comes to cleaning up, if he is bringing another woman home he is a fool, you will find other evidence.
Viagra, I can confirm that it works, as long as your partner is enthusiastic, if she is not keen, maybe a bad back or some other problem, it just increases frustration to both. So if he has found a really hot new lady no need for blue pills.

If he walks in the countryside there could be horses that he pets (pats?)
Or Black sheep?
Perhaps he's a gay convert! Nothing wrong with that!

I feel a bit sorry for him (and you too, of course). He does things to help around the house, can't keep an erection, so watches some porn, but you think he's up to something with someone?

The hair could have come from you, surely? Has he given you any real reason to suspect him of having an affair? If he has erectile dysfunction, would he be able to have an affair?

I wonder if the porn issue and the lack of sex are contributing to you feeling insecure? TALK to him. Invite him into your bed, get close, without sex, and see how things are. If you both think you'd like to have an active sex life, get some Viagra (you can buy it now, I believe)

Buy some Viagra if your sex life has fizzled out. It could be that his " drive " has slowed down and he's busying himself with outdoor pursuits to help him cope. It doesn't really sound to me that he's wandering. Give him some encouragement it's a two-way thing.

Just a thought!
You say he walks a lot and shoots.
If he walks in the countryside there could be horses that he pets.
If one had a black mane, could it possibly be that?
You have to think of all innocent reasons for the hairs but if you are suspicious, I would not mention them.
If things are not as they should be you will soon begin to notice other things.

Before you start investigating you need to decide what you would do if he was seeing another woman, as you
really were not happy with porn an affair would be worse.
You checked his computer, if you have access to his phone has it got a tracker, some cars have a tracker app, or you can buy a tracker. See where he goes. Just check how many cartridges he is using for clay shooting, 100 or more a day if he is keen.
Retired at 53, you working, his opportunities are endless, on the other hand it may be nothing.

Not you aggie, the OP who said she was furious with her husband for looking at porn. She says her husband has problems maintaining an erection. I don't see a problem with him using legal porn if it helps him get around that problem.

I am not in a rage .... but it is not a big step from pornography to abuse , and it is degrading . I am sad rather than angry , what in my post made you think "rage" ?

Sparklefizz. What do you think the scenario is? I think my view of it is what the OP thinks it is.

aggie. There are many things in life which exploit humans against their will - the chocolate trade for one - the West's insatiable greed for cheap clothing another. Do we stop buying chocolate and cheap clothes? No. Pornography is there and people use it. It's nothing to get into a rage about.

Oh come on the poor bloke Oakleaf now has him hung drawn and quartered You ve got a pretty vivid imagination oakleaf

Oakleaf How helpful is your comment? Talk about worst case scenario ....

Porn isn't victim free , it involves sordid film makers filming real people , and not necessarily willing people . It degrades humanity

There’s nothing wrong with using pornography so long as it doesn’t involve illegal activities. Getting furious with him over that won’t have helped. If you are certain the hair is human then sounds like he’s been to a contact site and brought a woman into your home. There are many, many sexually frustrated married men out there doing this kind of thing online. He may even have paid for sex. It’s worse he brought her into your home and didn’t go to a hotel but it’s done now. It’s just sex. Talk to him frankly about it. Look at some porn together. It may rekindle your own sex life.

If you " tackle " him it will then give him the excuse he's waiting for and will push him further away.
Reverse psychology is the way to go. That'll baffle him.

I would imagine that he'd have noticed the hairs first and disposed of them before you noticed. That's called covering tracks.
Just ask him,with humour,has he suddenly started sprouting long hair like a gorilla because you found a couple ( haha )

Well the OP hasn't got back , so Oldbatty might have a point

Why would you think that oldbatty ?

Do a DNA.! Perhaps they're not female.!

How is that helpful oldbatty??

Hairs can look much darker against (say) white tiles so I wouldn’t assume they belong to anyone else . Especially if that’s all you have to go on . Having been cheated on in the past I know I would recognise the signs these days. Paying more attention to appearance , avoiding any kind of intimacy ( not just sex) , trying to make up for guilt in other ways ( I’ve made your tea, bought you some flowers etc) plenty more signs to look out for than just a stray hair .
