I hate this part :(

Me and this guy were dating for 8 months. And I mean from day 1 we were only talking to each other, we weren't dating other people, held hands in public, were intimate, etc. Every thing a couple would do we just weren't labeled. Loved his affection towards me. I just became so comfortable with him like no other guy has made me feel. Of course we did have our downs as well. We fought a lot! We stopped talking for a month or 2. I started dating again during that period but somehow we found are way back together. This past weekend was just the worst. We had a huge falling out and said things out of anger and we both decided to call it quits. I admit my attitude sucks :/ But I find myself missing him so much already! I've been so down, and I keep looking at my phone hoping he messages me. And I don't want him to walk out of my life just yet. At the very end he ended up telling me that we should just take a couple days to compose ourselves and think about things to see what we really wanted. Obviously I still want him around. What are some ways to help control my temper? After all the fighting is it worth it? Advice please.
