he is depressed, not thinking rationally and confused. he will not get better until be is in treatment with a therapist and/or meds. even then it's a long road. you have been together for 8 years. that is a long time. but do you want to spend even more years with this confusion, possibly infidelity, lack of love, and so much more bad stuff. if you have already broken up i would suggest to stay strong and move forward without him. he needs to find his own path to recovery. you can't help him no matter how much you want to. i was with my DH for 10 happy years before he got depression. the last 5 years with depression has been hell. it's taken a huge toll on me as depression does to the partners of it.
