Do I walk...

I have been with someone for seven years. From 15-22 and have loved him more than anything. Last night we got in this huge fight over this girl and he just stopped replying. It is now almost four pm and he still isn’t answering me. I’m tired and drained from this. It happens far more than it should and him ignoring me is a thing everytime we fight. I can’t do it anymore. Should I just end things. I’m scared I won’t find love like this again.
