I need advice on a relationship!?

OK. SO the guys name is Shawn. We stared dating on Nov 27 of 07. We broke up 3 weeks later. We have been talking alot. Sometimes when i make him mad he blows up at me and yells and makes me feel bad. However he is trying not to do that. He tells me he loves me and says he wants to date me but then he says that he knows we wont work because he is going to screw up. I tell me that he doesnt no that and then he just gets mad at me. I dont want to think that he is just telling me he loves me so i will get off he back. I just dont no what to do. I recently found out that while we were dating he cheated on me. Can anyone just give me some advice please?I need advice on a relationship!?
It's obvious that he does not want to be in a serious relationship because people that do make changes. Simple as that.I need advice on a relationship!?
Stay away from this guy. He has serious anger issues and he already has you believing it is your fault. He cheated on you. He is the kind of guy that will only get angrier as the relationship progresses and maybe even get physical with you. He will say things like, ';See what you made me do'; and ';Why do you make me so mad';. Please get away from him now. You deserve better.
Why are always on his back giving him a hard time, maybe that's why he cheated. you can change a man, but gaurentee you won't by nagging, he will just yell, cheat and leave.
Why would you go back to him if he cheated on you? You have to be careful with tempermental guys. It's hard to tell what sets them off.
once a cheater always a cheater so move on
your advice is kick him in his balls , u will feel good after this
dump him if this guy is yelling at u and making u feel bad about ur self plz dump him look my ex boyfriend would do that all the time and yeah he would say im gona change and im not gona do that no more but he didn't it got really bad until the day he was about to slap me and so I called it quits. Look if he gets mad for every thing just dump him theres more people out there for u belive me I found somebody who treats me with so much respect. O and if he cheated on u once its pretty sure he'll do it again.
listen you guys only dated for 3 weeks and in that SHORT period he cheated on you. you never had him in the first place, u seem like a good person so why get into a relationship which was doomed from the start. it seems like he has no direction and very confused and does not know what he wants. dont get into a relationship and et hurt down the line because then you would ave wasted your time. find someone that really cares about you. remember that love in a relationship alone will never make you work, you need trust and you need to care about the person( clearly he does not care cause he cheated on but he might love you) Ultimately you know more than me just make the right choice. you can do much better and be much happier.
