Hooking up with someone

So I was with a guy for 6 years on and off but the last 4 years straight. 3 years of it i lived with him. we recently broke up. his decision. I tried to change his mind but didn't work. we have a little girl together and I didn't ever want to be separated as a family. it's been about 2 months and I'm over it after some things were said that I can not forgive him for. ANYWAYS.... I've been kinda talking to this guy he seems nice and if like to get to know him but I also don't want to be in a relationship any time soon. kinda just want to do me ya know. and he initiated some kissing, and a lot of pressured movements from down there. I went with it cause I was really craving it. But ended up telling him no. and I went home. But I reeeeaaly wanted to. is it too early to hook up with someone. I don't want to go around and sleep with everything i see but I also want to move on so he would be like a rebound kinda. what do y all think. honest opinions are welcome!!
