How to win your husband back?

I was feeling abandoned and as if he didn't care about me anymore. I always went out alone he never took me anywhere. One day I decided to kick him out and he left..My whole reasoning was to see if he would miss me again and we could fix things..but now hes with some other girl..I'm happy for him because I do love him and if he was unhappy with me than so be it but..We have a 2 year old son and I really want to work things out I love him him will all my heart and I guess I shouldn't have been impulsive and now I'm paying for it. I've seen him several times with this girl..He says they are just friends but I'm not sure about that..I asked him to go out to dinner with me today and he accepted. Whenever I talk to him hes like "im not sure if I want to do this again." how do I make him fall in love with me again without pushing him away. Should I just stop talking to him and only talk to him about our son or what? I don't know what to do..Hes been out the house for a month..and hes living at his moms house..he says he is going to start a business and get a house and blah blah and hes kind of insinuating that our family held him back. I hate some things about him but I love him..I need to go to counseling haha I sware maybe I'm just use to be being with him..after 10 years its hard to adjust..
