I need advice plssss, should I come back with my ex?

(I'm a girl btw) Okay so I was dating this girl. She was my first relationship and she was absolutely perfect. Before her I didn't even know I was bi and I just dated her to try dating once and didn't actually take stuff seriously but she gave me all the love I could ever want so I just learned to love her as well. Except she gets jealous really fast and was extremely jealous of my boy classmate because we were once in a situationship but didn't work out and we still stayed friends. They actually had a fist fight in our library once and I almost fainted trying to break them apart. And like we always fight from the smallest stuff, she just always buys me stuff after. Okay so fast forward to my graduation, she didn't show up cause she had to go see her brother who got his girlfriend pregnant and like we were supposed to have a date the next day and I didn't show up because I was still mad about her not showing up to my graduation. I haven't heard from her for months after that, I just heard from her friends that she moved back in to her hometown. Months passed and I've moved on, I had a boyfriend and suddenly she entered back into my life. Next part in next post, ran out of words
