To answer all the questions you guys asked.
High school was 4/5 years ago. But I talked to him a little bit in college online, here and there. The last time I talked to him was about 3 years ago. And the reason for that was we were so busy with our own lives that time, that we didn't really have no time for each other. Now we both have some free time to talk and hang out. I don't know the main reason why he want to start talking and hanging out now. But he did say that it would be nice for us to started talking again. I don't think he wants anything on the side. And to be fair I was the one that made contact first. All he did was reply back by a text message. He does not have girlfriend but does have a child. But I knew that before and okay with it.
And he did say that he was a different person now. So who knows?
