Is it over or just a blip?

Unwanted, I might be jumping to conclusions so I apologise if I offend but quickly reading your post one thing stood out to me. Regardless of the facts you related you really struck a chord with my own experiences. You sound very down and sad, dare I say depressed.
When everything around you seems to feel against you and you cannot see any joy in the world then regardless of the loss of contact of your daughter (which must be so painful, almost grief at a loss in your life) I think you might need some professional help or support. When you spoke of going to bed because you could not cope...that was so familiar to me and its something I've done.
Nowadays many Drs surgeries are geared up to cope with depression and anxiety in all its shades and variations and a chat with your Doctor may open the doors to some gentle support. Feeling in a rut and just not seeing any reason to carry on with a marriage is desperately sad and to be honest not uncommon.
Not being able to talk to those closest to us is also part of the problem, I found I was quite unable to explain how I felt to my husband but once I had talked to a support service it gave me the chance to open up to him. He, bless him, had not really understood what I was going through but now understand me better. I do hope I've not upset you but your post took me back to quite a dark place. I do hope things improve for you.

I agree with Mamissimo talk to your husband even though it may be painful for you both. You need to be honest about how you feel and how you can make things better. I think its the wrong time to consider leaving whilst you are both so upset.
Flexiblefriend is right, plan some outings and treats for yourselves and get on with your lives, hopefully your daughter will get in touch before too long.

You sound thoroughly fed up and that's not the time to evaluate your life and relationship. Make small changes, there's no reason why you can't plan ahead and do something on your next day off. Your OH might be as fed up as you, yeah shopping needs to be done but it's hardly a day out. Talk to him, say you feel fed up and stuck in a rut and would like to do something different for a change. Plan a drive out into the country for a walk and lunch out it's not ground breaking but might liven you up a bit. You daughter has moved on but she may well make contact again in the future but you can't put your life on hold until she does. So start concentrating on the one who's still there, can you think of something he'd like to do with you and start talking to each other.

Perhaps your husband is as baffled and upset by your daughter's behaviour as you are, and it can be more difficult for me to talk about emotions and family matters. Instead of pulling apart, why not try working together to get over this (hopefully temporary) situation you find yourselves in? What about a compromise of say, shopping in the morning and then taking yourselves out for a spot of lunch later? Or buying something nice for lunch and eating it, together, in the garden? Don't let this ghastly person that your daughter has hooked up with spoil your relationship with your husband.

Get out to the shops----with a few bob to hand. Always did the trick with me and it's surprising where the time goes especially if you stop for a snack somewhere or get some M&S sandwiches and head for a quiet spot.
A bus out of town too by way of a change.

I think you need to talk to him! How can he compromise and fit more with your ideas if he doesn’t know what’s wrong?

He will be hurting too and trying to deal with your family situation and may be very unhappy himself. You both are missing your DD and I think you may be missing each other!

Pick a time when you’re feeling calm and ask him how he is and explain how you feel and what you would like the pair of you to do. If you don’t ask you don’t get!

What I would try to do, is stand up for myself a bit more Unwanted. You should have stuck to your guns a bit more with having a relaxing day out on the Bank Holiday, instead of doing shopping, as you husband insisted on doing.
You mentioned that you have no friends to confide in, have you thought of maybe joining things or doing things without your husband so that you might meet other people?
Even though you don't have transport of your own, you could still get around by bus, train, coach etc.
So while you are at home this week, get out on your own, go to the coast and have fish and chips and an ice-cream, or get out into the country side for a walk, maybe go to a Museum in your nearest City.
Don't sit there looking at the four walls.
Live a little.

You can tell my Bank Holiday Monday was sparkling, can't you?!

Oops! I am getting confused! Today is Tuesday, not Bank Holiday Monday. That has gone. Ignore me.

I guess that could apply to a normal Tuesday though.

You must be missing your daughter terribly. I do feel for you.

I take it the shopping and going to bed was yesterday? Is there anywhere you can go today? Even if you have to go on your own, it will get you out of the house. If there are no events on locally at least going for a walk, perhaps by the river, or a park might help your mood.

I wouldn't be thinking about whether it is over or just a blip. Concentrate on today for now. Try to find a change of scenery, and perhaps a little something nice to eat. The important thing is getting out for a while.

Yes Unwanted, you can be lonely in a crowd....and what's lonelier than an unhappy marriage?
I don't like Bank Holidays.....they drag on. I'm divorced with 3 adult children, who do their own things and don't think of including me, probably because I'm not as agile as them.
But I did a bit of gardening, well, tidying up really, but the rain stopped me in my tracks and this morning , the borders worse than ever ?- never mind
