I don't know what to do

Hi! Does anyone have any advice for me, please? I (53 F) was in a relationship with a mother enmeshed man for 30 years (married, two children). I struggled and suffered before realizing the problem was his mother, because so much was going on behind my back. Last year my husband went to therapy and broke free from the enmeshment with his mother. But I suffering from depression, anxiety, and chronic fatigue. I'm in therapy for this and am slowly improving. My husband has truly changed, but I no longer want a relationship. It's very sad. I need advices. Sorry for my English, I'm Italian..
