DH and I will have been married for 22 years in September. We have 2 DC. Both of us will happily go out with our own friends, or go out together, or go out together with our joint friends. When the DC were small, it was more problematic to go out together, obviously, but we arranged babysitters and made sure that we had time together. It was very important for our relationship.
But what was also very important for our relationship was that we kept up our individual lives and friendships. It would never have crossed my mind to try and tell my DH that he couldn't go out with his friends, nor would he have stopped me seeing mine.
And the idea that we might bombard each other with texts wanting to know where were/when we were coming home is, frankly, ridiculous. Because we trust each other, and we are grown ups.
zealey - I'm taking you at face value here and assuming that your tone/style of posting is a slightly awkward 'how do I talk to these Mumsnet women' one, rather than being deliberately patronising and offensive. It sounds to me like your DW has become too focused on her role as wife and mother, and has forgotten that she needs to remember who she is as a person. It sounds like she is trapped in her role to some degree. She also sounds like she is terribly insecure in this place though. She is fearful and resentful of what you are doing and why and what will happen. I think.
I say 'I think' because of course I don't really know. You haven't really explained the situation that clearly or answered many of the questions here.
Has your wife always been like this, or just since you had children?
Were you ever 'allowed' to go out on your own or did she always want you to do things together?
How often are you expecting to be able to go out with your mates?
Are you an unpleasant and inconsiderate drunk?
I would hate to have a partner who was resentful and controlling in this way. But if he was, I would want to know why and what was behind this behaviour. I would also be worried about my partner. Whereas you don't seem to be worried about her, just the fact that she is behaving in a way that is irritating you.
