First, thanks to everyone for the comments and suggestions.
You also haven't mentioned your daughter in this. How does she fit in? Is she happy or not? Mummy's or daddy's girl? Where is her journey, still at school, getting ready for college? Many questions I probably shouldn't pry into, but you need to ask.
My daughter's 13. And she can be a struggle, as most 13 year olds probably are. Though I can honestly say that really has nothing to do with my current malaise. And my wife's patience with her isn't the best. She gets frustrated quick. It's not the cause of her issues, just another symptom. You know, though, thinking back, that was how old I was when my parents split up (I was actually happy they split up--it wasn't a healthy relationship). I guess that's one parallel--though I think it's just a coincidence as this has been something that's been building for a few years now.
My wife isn't a bad person. She's just always tended toward the negative end of things, glass half empty. I don't wish her any ill. It's just over time I find it's dragging me down as well. I am generally a positive person. And I used to try to get her to look at the bright side.
And I freely admit to my own faults. I am certainly not perfect. I can be guilty of stubbornness at times (if you've seen debates I've been involved with here you'd see that) and I can procrastinate. She accused me of laziness, but I honestly don't think that's the case. I do my share, but it might be before I go to bed instead of right then and there. I used to even argue my case, but I don't anymore. I just listen and don't really put up much of a defense anymore. I don't want to sound harsh or insensitive, but I find that I don't really care anymore.
I concur--if you can, talk to a counselor. Why not be open about why you are going--nothing you have said here is anything that should not be said to your wife. In fact, hearing you describe her and your marriage, I think these are things she deserves to hear and you both deserve to work on and/or work out (I think you've been very thoughtful in what you've written about her). You have expressed concern for her happiness, noted that she's a good person and great mother (even when it's challenging), and are noticing that her temperament has changed over the years. You have expressed feelings of loneliness and having to hide your feelings in your marriage. To say "I care about you and you deserve happiness," to both her and to yourself--it's hard, but it's true.
1. Is part of the reason your wife is unhappy all of the time because you aren't what you "sold" her leading up to your marriage? If so, is the reason you aren't because you never were, because she had her own false expectations, or because you aren't putting in the work to be? The answers to these questions might point the way forward.
You guys have great suggestions but I can't help but think of that scene from the DS9 episode "Battle Lines" when Kira starts berating what's his face (Shella, or whoever was the leader of the group they were stranded with) about their defense strategy. He looks at her with what I thought was a bit of regret and amusement and says "We used to defend ourselves better...". I haven't talked to a therapist but a lot of the other things you suggest I've tried. I used to try talking to her. Telling her how sometimes it'd be nice if she just said "I love you" or take a walk holding my hand instead of yanking it away when I've tried. I'm not talking about PDA or anything. Then over the last 4 or 5 years I slowly gave up. And now I've just hit a wall. She's a good person. Our relationship problems doesn't mean I think otherwise. And I'm no saint. But over the last few years I've come to the conclusion she'd be happier alone. If we ever split up I honestly don't think she'd want to get in another relationship. She has her own way of doing things and I just think she'd prefer things that way.
Now as I've said before, I've been pretty good at faking it. Pretending everything's fine, esp. to the outside world. But I guess this funk I'm in was inevitable eventually. You can only pretend so long. This dream I had and these thoughts were probably a catalyst to wake me up to just how unhappy I've become. Over the last 2 or 3 years I've even thought of things I would need to do were we split up.
So why are we still together? Part of it I think is her parents. They've always been good to me, no in-law problems here. But that's part of the problem. They'd take it very hard, and would probably be angry. They're a bit old school when it comes to marriage. You don't split up no matter what. I don't think they'd understand that neither of us is all that happy anymore. I mean, I expect them to take her concerns more seriously. They're her parents, I'd be concerned if they didn't. And I don't want an ugly separation. I'd want things to be cordial for our daughter's sake, and I'd have every intention of taking part in her life. And part of it is probably convenience. Splitting up requires a lot of work, let's be honest. And it's not an abusive relationship by any means, so we just go round and round and grow more distant with each passing day. And I start thinking about things some have said in another thread about wishes about how nice it would be just to have someone who's happy to see me at the end of the day, who says she loves me now and again and maybe go out and take a walk together. And I feel so alone.
We were happier once. None of this happened overnight. But as time goes by I start thinking more and more that perhaps our relationship has run its course. It's something I'll have to really think about. It's obviously not fair to either one of us to just go through the motions and pretend everything is ok. Perhaps a time is coming where I should let her go her way and let my self move on.
