So many thoughtful helpful responses - I'm really touched.
NoOneElse you've given me a lot to think about. I think the truth is that DP and I were pretty fucked up individually, when we met. I know that I have damaged my DC's mental well being. The dynamic between DP and me has been fucked a lot of the time - not all the time, but too much of the time. I feel terrible about it. The best thing, most caring parental thing I guess, that I can do now, is grow up myself, take responsibility for being a calmer and happier person, and stop fighting their DF about stupid things.
MoreProsecco yes I read some of that thread. I think my DP is highly passive aggressive, it's weird everyone thinks he is so lovely, and he is. But just tonight, DS has the flu we are recovering from. DP goes to his car, comes back with panadol for DS. 'We have some in the bathroom honey' say I, 'you didn't need to go out to the car'. DP says 'Oh yeah but I can't find anything in the bathroom, it's easier to get the stuff out of the car that I bought so I know what I'm looking for'. Now in our dynamic, that is a loaded response, imo.
DP won't drink tea if I make it, because I don't make it right. Fair enough - some people are particular about their tea. But he won't eat meals I prepare, either. He will say 'I'm sorry Notsclue, you know I'm an old fuss pot' (sad dog face) ; or 'I ate on the way home' (then makes himself beans on toast half an hour later despite there being a perfectly edible veg curry) or 'I'm feeling abit queesy at the moment I might have some later' and never does.
Littlebit yes DP has made himself an ally of DC by being unchallenging, undemanding, setting no boundaries (other than health and safety ones) and being the one who is 'the victim'. Maybe he is - but I also know that he actually has a lot of anger which he denies, as I hear him muttering and swearing eg after ending a telecall with his own DM.
I think there has been no fully developed adult in our family. DP is indirect/machiavellian, and gets what he needs 'under cover of darkness (his own phrase); I'm needy, dependent, and a coward.
Those of you who have said 'go!' have really helped me decide stuff. i have cancelled some pending work on the house which I was set up to pay for, and have booked two trips away later in the year doing stuff I really really really want to do :)
I have connected with a charity that wants people to teach English to young girls in Laos and after I've sorted some stuff out with my business, I will be booking up for that for the autumn.
THose who said, keep the door open with the kids/don't flounce, I hear you! I have talked it through with DP (and I do care for him, he's got some great qualities) and then later this week when we're not all dying of flu, I'll brief the kids along the lines of 'I love you all and want us all to be happy, including me, and you know I've been wanting a big adventure... here's my plans for the summer/autumn, we'll be together therefore for the next 5/6 months. We're each of us going through a big changing point in our life (DP retired last year) and so I want to agree some new ground rules while we carry on living together, to make for as relaxed and happy a home as we can - '
So I feel calmer, less 'engaged' if that makes sense, and definitely more excited about my own future :) Thanks
