I'm now talking to my ex?

[ohnana]

So I broke up with my ex because he gets drunk all of the time and he called my best friend a bitch and so I broke up with him because I didnt want him to act that way towards me in the future. anyway besides that, I broke up with him September 26 and I deleted him from my facebook and his number. So last week I posted a comment on my facebook saying that " I caught myself thinking about you" then my friend commented on it and she asked if I was talking about my ex boyfriend and I said yes..I took her advice and decided to talk to him again. I added him and he commented on my like my picture and wrote on my wall saying "happy holidays" then told me to text his ass, I text him and we just asked how the other was doing and said about two words about the new year...should I still try to remain at least friends of just go on? any advice, MEAN COMMENTS WILL BE SPAMED
