Should I move out

How have you managed up until now?
21 years is a long time. I'm sure all marriages have their ups and downs.
Personally I wouldn't want to share with 5 dogs but then I wouldn't want to watch sport on TV all day either.
Sounds like you are in a rut and need pulling out. Are you sure relate would be no help?

Is the issue that you watch things on TV and your husband is complaining that he can't watch anything?

I don't think you need to move out if this is the case.

You could get another TV and put it in another room of the house so you can both watch TV.

Just re-read your post, he's a selfish sport? Try this:

And five dogs, he might not be ok with looking after them all on his own. Even one dog is allot. If you split you could do play dates for the dogs. You could take two dogs each the last dog can go either one of you. then every now and then let the dogs meet up in a park or something

is this genuine please? Anybody?

If your life is boring why not go out and do something?

I’m afraid I don’t really understand the problem.

My dh who I love dearly would be happy to watch sports all day, but he doesn’t. He knows we have to have a life. He has a hobby that takes him out 2/3 times each week. I meet a friend for lunch and also have a hobby. Dh and I also go out at least once each week that is not for the shopping.

I’m sure many times he’d prefer to watch sport but knows that it would be selfish. He also knows that if it got too near my ‘sports boundary ‘ he will hear about it. Guess it depends how cooperative op and her dh can be.

Doesn’t sound like it has been properly discussed and sounds rather as though op has a negative attitude. Apologies op if I am wrong.

TV channel choices seems a bit trivial to be considering separating/divorce, is there more to it than this?

Extremely trivial, in my opinion, plus not compromising by watching TV in another room.

Surely absolutely no one considers something as serious as divorce over such a minor issue??

I'm a bit unsure what the situation is Vauxhall Do you really want to leave your husband or are you just fed up with how things are at present.
It's not always easy finding a rented place which will accept dogs so you need to consider this if you are leaving, could you afford a place on your own?
Alternatively could you not lead more separate lives, make a room into a nice bed sitting room for one of you with TV and comfy chairs etc. You could find activities outside the home to enjoy and socialise with others.

Wot, don't you have anything constructive to say ? I don't think punctuation was foremost in her mind.
Vauxhall, so sorry about your situation. Been there, got the medal.
Not sure about your financial situation, but make sure you are able to stand on your own 2 feet. Do you have adult children? I know it's hard. When my husband and I divorced, I made sure I kept our pet dog. Mind you, me ex didn't want her anyway. The only one he wanted was his mistress.
Good luck Vauxhall

It might not seem fair to have to watch a tv in another room, you can always just continue as you are .... watching sport and reruns that you don’t want to watch. I’d go for the other room. Unless you can change the attitude of your dear husband. Do you think this is possible? Have you discussed this with him.

Is there room for a comfy chair in another room/your bedroom. Would dh perhaps be happy to watch his sport in the bedroom/another room?

Sorry, meant to add that sex (or lack of) isn't the be all and end all of a relationship either.

TV channel choices seems a bit trivial to be considering separating/divorce, is there more to it than this?

Punctuation?

No I don't have many friends at all and I don't see why I should have to lay on the bed to watch another tv just don't seem fair

Could you afford a private rent on your own ? Something to think about.
Have you talked to him about this, maybe he dosen't realise how close you are to leaving. I would have a chat and at least give him chance to change.
Do you have hobbies which get you out of the house, friends to visit and go places with ?
Do you have a spare bedroom that you could set up as a TV room for yourself ? If not I would at least install a second TV in your bedroom.

Lot's of questions, sorry.
