Hi world, im in a complicating situation and i need advice?

[Jazmin]

I met this guy in high school my freshman year abd we've been at it for about 3years which makes us seniors this year. During our relationship, I would always break up with him over little things and he'd always beg me to come back and I always would. I'm like the classy type and he's like the thug type.. we've been through a lot and just about few months ago he cheated on me with two diff girls because he said I stopped paying attention to him and putting my friends first.. which I did. So I found one of the girls on twitter and we had our arguments theb yesterday I saw her in person for the first time and we fought and I blamed him for it all and told him I didn't want anything else to do with him. . I haven't talked to him since, I've been ignoring his calls. I really miss him and just want him to know how I feel about him. Was I wrong for leaving him? Should I try to get back with him what do I do?
