I sympathise lj i really do- i haven't read all of your posts but i wanted to throw something into the mix. It is NOT a criticism, just a question (i would probably feel the same about my DP if i were in your position). But i would just wonder, all those things you said about him not being motivated, not having identity etc etc , well it sounds like xenia posting about SAHMs. I am a SAHM and do find motivating myself hard, i probably don't do as much as your DH but no one criticises me for it. I mean, they wouldnt dare, would they!
It sounds to me like your DH has got into a rut - personally i would be hopping mad about the golf (whats that all about??) and i would want my DP to either have DD at home or work. But, speaking as someone who should be working as we struggle financially, but has lost her confidence it IS hard to motivate oneself.
I don't know what to suggest.
Ive always regarded SAHDs with high esteem, don't know why, they are only doing what millions of women do day in day out. But it always seems such a positive choice for the men, the ones i know really love it. I guess you have to be pretty sure of yourself though, SAHMs are made to feel inferior so to be a SAHD is probably not good for the ego.
I think you should talk to your DH and say that whilst you are happy for things to stay this way at the moment, you do not want this situation to continue. He really should either retrain, study or get some part time work while DD out of the house. What about voluntary work - not working in a charity shop but something positive and challenging, comittee membership or something?? I would love to do that, but childcare would be a major issue.
Good luck - don't let this fester, he needs a kick up the bum, but do it gently
