How to deal with a fuckboy 😳

So I'm talking to this guy and I'm not 100% if he's a fuckboy or not. Mainly because he's nice one moment and then he ignores me the next. A few months ago he got angry with me but he apologised later because he was in the wrong. I Lowkey like him but I'm over his shit but I'm to nice to say so. He's also going to the army in a few months so idk if I should just keep taking to him until then or what
