dont know what to do..hurt

wow..i am so hurt..i got a phone call i wasnt expecting..i got into a relationship and after about 3 weeks i was feeling very jealous..some of his actions were not matching his words and i wasnt sure of anything..well saturday he just stopped calling and never kept the plans we made,,i thought i was being played ..and i decided it was over..but i couldnt get ahold of him to tell him..last night(mon) he called me late and told me what happened..he brought his daughters to a bday party and his ex wife was there,,she wanted to talk,,he said that she told him she wanted to work the marraige out and wants him back..he said he left and took off,,he called a guy friend and went out of town to escape and think about things,,he still has old feelings for her and doesnt know what to do..he said he told her that he had other things going on(me)..he treated me well and i know he cares for me..she abused his children and after only 3 months of marraige she up and took off on him with another guy..what the heck am i suppose to do,,what can i do? do i trust if i just let him go he will come back..do i plead with him not to return to her? do i even give him a chance to come back after this,,its only been 5 weeks since i met him,but we spent alot of time together when we could,,we like the same things(mostly)..i have serious previous hurts from the past(some more recent than others)...this hurts so much..i fell really hard for this guy when i didnt want to..i had a wall up to men and relationships and he just burst right through it very quickly,,now im left alone to try and build myself up again...the saying is if u love something set it free ,if it comes back its yours ,if it doesnt,it never was....what do i do?

If you were asked your opinion about the viability of having a relationship with a man who is considering going back to an ex that abused his children and left him after three months of marriage for another man, what would you say?

I don't think it would be very wise for him to go back to her. Only three months of marriage and she just took off? How unbelievably selfish and cruel. She doesn't deserve him. She doesn't deserve anybody. If he gets back with her than she's going to cause him much more heartbreak and pain.

um,,idk,,i really dont know how to answer that..probably that it wouldnt work because he is searching for some kind of acceptance that he wants from her......maybe if you could rephrase the question i could get a better view of it....ty byz

I personally don't think that he is ready to form a new relationship with someone if he is having mixed feelings about his ex. I think he needs time to himself to make a decision on what he wants in life and I don't think it is fair to you if you two were to try to start a relationship at this time. I do think you should set this one free and if it is meant to be he will be back with a clear mind and his past behind him.
