Ex boyfriend out of prison?!?!?!

Well rumor around town is that my ex is out of prison. So thats not good. Well i dont know if it is or not. Its weird for about 2 weeks now he has been in my dreams almost every night. Well he got out about 2 weeks ago. How strange is that? I wanted to write him in prison so bad because i felt like i still had so many things to say to him. My dad and i were talking about him the other day and he asked me if i still like him. I told him that i just feel like we didnt really have an ending and i feel like i still need to explain a lot of things to him. He doesnt even know that i am pregnant. I was going to write him and tell him but now that he is out i cant do that. I want to talk to him so bad, at least so we have an ending. I mean what if i were to ever run into him on the street or something? What would be said? i am pretty sure they wouldnt be nice words exchanged. I am friends with all my exes, I would really like to keep it that way. I feel like i wanna drive past his house and get the home address and write him with one of my friends return addresses, that way i can know how he feels. But im scared that my boyfriend John will find out and get really pissed. What do u think?
