cor this is a complete nightmare and it's driving me mad.

Ahh I don't think there is any solution to this but I'm in an impossible situation and need to have a rant haha. it's a very long story but I'll try to keep it short!

Basically, my boyfriend of a year and half broke up with me this summer, but the next day told me he didn't think he could do it after all, and I, being very naive and silly, proceeded to let him have his cake and eat it too - we both stayed single but ended up sleeping with each other everytime we met up He kept saying give it a bit more time and he'd get back with me, and that he loved me, didn't want anyone else blah blah, but I'd always feel so used that I used to argue with him all the time which didn't help much...

Anyway, I eventually just decided to move on and met someone I really liked who I'm now with, but the unfortunate thing is, he's with someone else now too, which just so happens to be my new boyfriends sister! What are the chances eh. It's absolutely awful and I hate it. It's like a game of chinese whispers where everyone seems to bitch about each other and then find out warped and twisted versions of whats been said and I just don't want this right now at all.

What angers me is that I've said I'm happy for my ex boyfriend, and that if she's anything like her brother then he's obviously picked a wonderful person to be with. I just want us to both move on and be happy and be friends.. But my ex boyfriend, through immaturity perhaps, refuses to be my friend and has proceeded to spread nasty and vicious rumours about me, and his new girlfriend has said downright bitchy things about me without ever meeting me! He's told my new boyfriend that I'm not over him, that I constantly pester him, and that I don't want to be with him and that he's being used and I don't see why he felt the need to do this! I've been accused of only being with him for the sake of it and not actually liking him, but I've just chosen to handle things differently - I'm young, I don't want things to get too serious too soon and I don't want to make the same mistakes that I made with my ex. Also his new girlfriend/ the sister has completely judged me by the false impression my ex has given her and constantly complains about me 'always being there' and 'harping on about the past', and has also accused me of messing her brother around yet with nothing to back upwhat she's says except what my ex has told her. I'm really hurt and upset that she's said these things about me, but I don't want to be nasty about her because obviously she's my boyfriends sister. I made a passing comment to my boyfriend about how I was shocked they got together because my ex said he didn't want another girlfriend which then get turned into me saying he didn't want to be with ehr and that I was trying to break them up! argh its all absolutely pathetic, I just want to get on with my life and not have to put up with this bitchiness!

So I just don't know what to do, I don't want to walk away from a really great guy who I really like because two people are spreading nasty things about me, but I just don't want all this hassle and unkindness all the time. She is at uni and he's not so I doubt it will actually work, but for the time I'm stuck not being able to get on with my life becuase I've got my ex and his new girlfriend making snidey remarks about me constantly and I can't even be annoyed about it because I don't want to cause problems between my boyfriend and his sister! Ahh i just don't know what to do. It's a complete nightmare
