Should I began seeing this other dude and take it slow?

So… There is a guy I have been w. for the past year. He has a cute little baby girl by his ex-girlriend. I knew him before we got together we were good friends. His Ex is psycho. She lies like hell.

We broke up. Over drama that taken place He told me that he wanted to still be w. me but it was going to take time to get all his business together.I agreed and at first after the break up we still spent a lot of time. We agreed not to see other people and all. Then he up and changes on me and I get upset. So I just stopped contacting him.

We have not talked in a while about wether or not he wants to get back together. I have not seen him in 2 weeks. He contacts me from time to time but never really waiting much but to see whats up w. me.

I said we agreed not to talk to these other people but since we havent really spoken about that I dont know whether or not to say hey and began dating this guy I met or to wait on him…Which he said shall be no longer than 2 mnths. and its already been a month and a half.

Should I began seeing this other dude and take it slow? How should I go about talking to my ex when he is acting the way he is? Is that a sign of him not being into me like before or what?

I am completely lost someone help.
