Pointless arguing

I've been seeing this guy for about 6 months. It seems like all we ever do anymore is argue and the last couple weeks we've barely been talking. The arguements are over little things like me going to bed a little earlier since I have a lot to do and am very tired instead of staying up to talk to him or not being able to call him because I'm in the middle of something or not being able to go on a last minute date with him because I've already made plans with my friends. He hasn't met those friends of mine yet and he asked me for their numbers and is always bragging about all the "pretty girls" he's seeing when he's out. I don't know why he's doing it all of a sudden. I tried to talk to him about it, but when I brought it up, he ignored it and changed the subject completely. I don't know what to do.

I would sit down and tell him that you all need to have a serious talk about the relationship and where it is going. it seems like he wants more of your attention. and by mentioning the "pretty girls" its like he's trying to make you jelous so you will be around him more. tell him you don't want to argue anymore and that you just want the relationship to work. make it clear that you want him and only him and that you do have days that you want to hang out with just your friends. try to make time to talk to him at the end of the day. ask him whats on his mind. be there. also make sure he's there supporting you also. i hope this helped.
