Ex-Boyfriend Problems?

Okay, so about a week ago, my boyfriend named mason broke up with me right before he left for a church trip. He said that he wanted to break up and that I should find someone that would make me more happy. And it seems like guys know exactly when a girl is single, because when he was gone, three other guys flirted with me and admitted their feelings for me. I feel bad because i turned them all down. I mean, I JUST got out of a relationship. Mason and I was dating for TWO WHOLE YEARS!!!! But we fought a lot. Now i dont know what to do!!! Mason is supposed to come over today to gather his stuff that i stole (Like PJ pants, boxers, his favorite lighter). But I still LOVE him! I'm still madly in love with him and i cant stand not being with him. I was screaming in my pillow for an hour when he broke up with me over the phone....What should i do...? If I get back with him, what am i going to tell the other three that like me...? I'm so confused...
