<human>: My ex-SO and I broke up, together for 8 months, because he was mad at me for a Facebook status. He ended up trying to "take it back" 6 hours later but I wouldn't allow it.

In the meantime however, it was my friend's birthday and I had had a crush on him for a little while because I've been so unhappy in my relationship, but I wasn't "allowed" to break it off. He wouldn't take it seriously whenever I said it so I was waiting for him to break it off because I knew he would get mad enough and do it eventually.

This friend and I have been attracted to each other for a few months, but he respected my relationship and never tried anything and I didn't go past any boundaries. We had only hung out with other classmates outside of school twice and I was being accused of doing it all the time, for whatever reason.

Anyways, he had been giving me advice on my relationship by trying to give me perspective from the Military lifestyle view and the guy point of view, so we had been talking for a while.

On Monday, it was his birthday and my ex-SO had broken up with me and all I felt was relief. My friend and I hung out after class ended because it was his birthday and we did kiss and make out a bit. I was ignoring my phone because I figured it was my ex-SO trying to "take it back" and I didn't want to deal with it.

As soon as I get back inside my house, he calls again and I answer and start telling him how tired I am of this and everything about our problems. He asked where I was and said who I was with.

Tonight, my ex-SO and I were talking because I was trying to be there for him because I knew he was hurting(somehow he translated this into "I will wait for you", which I had no idea) and we talked about that and I told him what happened. I'm being called a liar and a cheater.

Should I take any of this seriously? Should I just ignore it? Was I really wrong for what I did?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My ex-SO is accusing me of cheating on him after we had "broken up" and I don't think I did. What do?
