When I met dh he was in a dead end job with few qualifications. With support and encouragement, he became a mature student and got his degree. Almost immediately after graduating, we had our ds and I took maternity leave. Due to ds' ill health, I've spent 9 years taking any jobs that fitted with childcare. Dh has spent 9 years working his way into what he always wanted to do - but it's been a long struggle of temporary jobs/shitty pay etc. Each time we were struggling, I offered to return to my career, started looking/applying but then he would sort something out. This year, he finally got a permanent job doing what he's always wanted to do, but I'm going stir crazy! I still work part time, but can't return to my profession whilst juggling childcare. I'm limited to hours/location etc and I'm finding it hard to cope. My self esteem is in my boots and I'm getting depressed about it. I've spoken to dh and he knows how I feel (it's come up many times over the years, but he was always best placed to work full time due to my ill health and that of ds). He has said I can go back to work full time and he'll resign. But....he will have similar issues finding work around school hours, just as I have. The childcare options are few around where we live - believe me I've tried! So although he has said it's okay, I know he will start to resent me for ending his dream job. I don't think my need for a career should trump his, but I'm at a loss to think how to resolve this. I feel trapped and like I'm suffocating - I can't do this for another 10 years, when the youngest will be old enough to come home alone).
DH job won't consider part time/job share and to get back into my career, ideally, I need to do fulltime with shifts on a rota. If I wait ten more years, I'm unlikely to get back into it, and I'll be too old anyway 
So how can I rectify this situation without either of us being resentful of the other? Is that even possible?? I don't know if our marriage will survive as it is right now
