My heart is confused

Well on 10/25/11 me and this guy (Matthew) dated and we broke up in Late April. After we broke up, i dated a few other times . When i was comfortable and I felt as if i was completely over Matthew, i decided to become friends with him again since out friendship before dating was terrific. Okay, now theres these 2 guys that have feelings for me and I'm falling for both of them, but they're both so confusing. The first guy is so sweet & we flirt alot and he's just the kind to keep around. But the other guy, hes attractive and he knows what to say whenever i need to hear it the most. I wanna be with him but he texts and calls on and off so its hard to think if he wants to stay. The first guy is convincing that he wants to stay, but i don't really want him. The main problem here is that whenever i think i want a guy, sometimes feelings for Matthew just rushes back and i just don't know what to do .
