Making up with scorpio man, (scorpio advice)

My friend and I have been long distance friends for year. We used to date back in middle school but have always remained friends because of this distance. Although were both still flirtaious. Anyways This past summer we've been talking over the phone everyday from hours on end. We get along very well, i'm a pisces female. But sometimes we get in the most heated arguments. We have completely different perspectives on alot of things and he says alot of offensive, shallow, sexist and egotiscal things that really irk me. Not paticularly about me but just his attitude in general is like that not always though. Sometimes he'll show signs of caring about humanity haha. So of course I call him out on it when has a negative perspective and the one thing leads to another. Aside from that we sometimes get into meaningless arguments about nothing for no reason. Well the other day we got into another argument over the phone. I thought the argument was pointless and wanted to move on from it but he was so intent on continuing it even though I said I didn't want argue because it(the topic) didn't mean anything to me. And eventually he told me that the topic wasn't the argument it was my arguing tatics that pissed him off which I was unaware of. And hypocritically using the same ones as me when arguing about it. So again after telling him and him not listening,

i hung up. I've done this before but usually called him back to make up a few hours later. This time i haven't said anything to him for a week mostly because I needed space. This is the first time in 3 months we have spoken to each other on a daily basis. He hasn't called me back either.

Tonight I gave him a call and he picked up but hung up after i said hello. I called him back again it went straight to voicemail? I'm not even sure if its worth putting in the effort. Maybe its better if I move on? Sometimes I do really miss him as a friend.

Any advice?
