All I can say is that if you don't like the person he has become then it should make getting over him alot easier.
but I can't help but sense that despite everything you have said, you would have him back, and it sounds like he wants back..sorry if i am wrong in that assumption.
maybe the phone guy is right..
if you want him back, have a good period of no contact which it sounds like you both need, especially you.
either way, no contact is the way to go as it really is the only way to get over someone and move on.
I know that I would still be a complete mess if I was in contact with my ex. He said that he wanted us to be friends because I am his best friend, blah blah blah! - but we all know that really is a guilt-reducing exercise and not a genuine offer of friendship.
I reckon that when the say '..but I want us to be friends', they are secretly praying that we will say no!
I gave my ex what he really wanted - for me to disappear quietly out of his life as if I had never existed but I sometimes wish I had taken up his offer to be friends and actually made him do things with me, just for the fun of watching him squirm. ha!
you sound like quite a strong person...I think you will be ok.
