is it cheating?

So, I got out a long term relationship and about a month later I began seeing a guy who was about to leave for bootcamp. I was seeing the guy for about a month but told him that I wasn't ready for another relationship yet and that it'd be best if we weren't together while he was gone. While he was gone for 3 months, I gave another guy a blow job and had a drunken one night stand with a girl.
