Hi ~ To be honest, I like the advice the person gave you about going to therapy. I think it might be a good idea.
Please don't get me wrong. I certainly don't think you're crazy!!! But I think you should explore why you're so attached to a man who is 22yrs older than you. Plus you said that you were already depressed -- you need to find out the reasons for THAT too! Depression just doesn't "happen" -- there are reasons for it, and sometimes they go so far back as our childhoods. Therapy can help you find out WHY you were/are depressed and how to pull yourself out of it and keep it from happening again.
AND, you need to move on, my friend. You cannot keep obsessing about this man, and allowing your thoughts to keep being interrupted by him. You need to have a good life, free of him now that he's moved on. So please seek therapy, will you? You WILL be much happier, I promise. You deserve to find someone who will love you as you DESERVE to be loved, and who will STAY with you! Do this for YOU. God bless and please take care. Hugs, Lee
