DAMN HIM!!!11111 :'(

I hate my b/f! Well my 'ex' shortly! I was on msn today and loads of people started telling me that my boyfriend has been texting this other girl and ringing her for about a month now and telling her he loves her and he's going to end it for her. I'm so stupid! My friends keep telling me i'm too good for him, I didn't used to agree with that now I don't know! He lied to me saying that he didn't like that girl one bit, so in a way it's like he's cheated on me. I've not ended it yet i've not spoken to him. I've been told I should kick him somewhere if he asks me to get back with him but I want to know what you would do if you was put in that position?
