DH and I have been together nearly 30’years. Two teenaged kids. I am perimenopausal (49). Have been unhappy for years, our sex life has needed constant work as he is mostly impotent and won’t seek help for it, I have tried to be patient and supportive but tbh is feels like he is more worried about having an embarrassing conversation than about the impact of so much rejection on me. I feel on edge around him, he is very certain of himself and his views and over the years I’ve just shrunk myself to where I second guess everything I’m about to say in case he ignores it, or says it’s not something he interested in. We have similar interests, get on ok as people, and have come through some tough parenting things. I am thinking all the time now about splitting up. But I’ve been the one raising the kids and working part time so my income is about half of his, and my pension is shit. We live in London so housing is very expensive. What do I need to think about? Can we be fixed? If so, how? If not, what do I do?
