I met a guy and it got serious FAST what do I do now?PLLZ help 10 pts best?

I live in Oklahoma and met him in Indy. @ my cousins house.We are both going through divorces due to cheating. Long story short we started talking texting and have ALOT in common. We have talked so much that we started talking marriage and merging families. He flew me to Chicago so we could hang out, and yes we had , but we have both only been with our spouse ually b4 this. Things were great until e-one told him to slow it way down.( we have told each other we love each other). We get along like nothing I have experianced. Now he has decided to break it off to "make sure" I am the one for him.He has even pre-bought plane tkts. for us 2 see each other and bought me a cell phone so we could talk easier. So now he is dating other ppl. and I am devestated. We rnot tlking because he says he needs to figure this all out, but he wants me to keep the phone and he says he will not have with anyone else. What should I do? Wait for him? or send the phone back and go on...
