Big relationship problem :( Please help (10 points)?

I'm going to cut to the chase too. I don't know how old you are but it sounds like the both of you are very young. The reason I say this is because the behavior is very immature, and likely not going to change in the future. I understand you've been together for 2 years but would you rather have 2 years with a nice guy you can trust or 2 years with a guy who is always trying to get back at you? It's important to find a partner who you can trust day and night. A person who FIRST confronts you about something before he seeks revenge. And how do you know that he REALLY was seeking revenge or just using it as an excuse to do as he pleased? Can you imagine how awful of a person he must be to set it up waiting for you to find that flirtation on his account? Listen, maybe he will change in the future maybe he won't, but if you want my advice let this be a learning experience for him to lose a nice girl. You have another option if you choose it: you can stay with him and tell him how much this hurt you, how you were not doing as he thought and you deactivated your account to prove to him you are not after anyone else. Tell him you are proud of him for telling the girl he is taken, but it is inexcusable that he flirted with her and if you catch him doing it again that is the end of the relationship. Whichever choice you pick is yours only.
