Mac, I think you really need to sever all contact with his woman, draw a line under it and move on. I'm not sure why she sent you a picture.of herself and her boyfriend, but I can guess. Your search for a woman in her 20's is almost certain to end in disappointment. People on here have given you lots of advice but you've ignored it ( though keep going to the therapist). Man up, grow a pair, be realistic and join dating sites looking for women of your own age. Sorry to sound a bit hard and I am sympathetic but you need to see things as they are and not as they are in your imagination.
You say the you need a friend but I friended you and sent you a message but got no response. I'm sure people on here would correspond with you but that takes 2. Stop obsessing about this unobtainable 'dream' woman ,get generally more social (rather than sitting alone in coffee shops), join meet ups, join dating sites do voluntary work etc. But then people have already said that. I know you're a dreamer. Me too. But we live in reality. Or do we. But that's for another discussion.
