I’m in my early 50s and my husband is in his late 60s. I know the age gap is too big but we fell in love decades ago when it didn’t seem to matter. We have 2 children in their late teens. He has suffered from erectile dysfunction for years. I’ve finally realised that he won’t recover. I’m so sad and disappointed. I feel liked I can’t blow up a marriage just because of sex when, from what I hear, sex won’t matter so much to me after the menopause. But it does now. I sometimes think I should leave once the kids move out- aibu?
