So I have REPEATEDLY told my boyfriend since long ago that if he doesn't want to talk or if we're in the middle of an argument, to NEVER just hang up. But he still does, even after 5 years of dating. He just...hangs up. And when he feels like it's already okay on his side, he's gonna talk to me like nothing even happened in the first place.

Honestly, it's very tiring and I'm REALLY considering ending this fucking relationship. But if there's any hope in saving this, then I'll save it. I know I sound crazy, but how do you deal with people who just hangs up the phone when they're mad and then talk to you several hours later like nothing even happened?

To be honest, I am confused what is the problem here...

You were having an another argument about something and the guy felt that if the argument continues, it will get ugly so he decides to sop the argument but somehow that's a problem...

To me it looks like you are arguing with him for the sake of the argument and not to make a decision about a specific thing. I personally think that's kinda toxic from your side. Sorry.
