Do I have the right to say something about it??

Ok let me see if I can explain this... Yes some of you will think I'm stupid in the first place but hopefully we can get past that. When I met my boyfriend, his ex girlfriend still lived with him. They had been seperated for two months yet she still had nowhere else to go. Ok I put my foor down, in the first week she was out, moved back in with her mom. So they were together for awhile so they have bills together or whatever. Ok I get that. I made him at least stop paying her share of them which he did. The only thing he pays now is a loan they took out together. Of course she still calls him about stupid stuff. Any excuse to call him but itwas mostly about the kitten he got her last mother's day because she knew how attatched he was to that cat. Well last night she calls him and tells him that the cat is sick. (now this is after she's told everyone I'm fat and ugly, tried to run over me in the car, found me on myspace and made an account JUST TO SEND ME A MESSAGE!! so on and so forth) and that she wants him to take them to the animal hospital about an hour or so away at 11 o'clock at night (he was at work). So he calls me to ask me about it and asks me if I would be comfortable going. I said fine but she said hell no. After a back and forth argument her dad finally takes her and by now the cat is dead. So he comes home from work and tells me about it so I try to comfort him. We lay down to go to sleep and she calls at 12:40 at night knowing both of us have to get up at 5am. She's crying or whatever and he's trying to calm her down. For some reason the main thing that sticks out in my mind is when he said "I can't hold you anymore". I don't know why but I've been stuck on that all day. He told her to just calm down and get some sleep. So they fight a few more times and he finally says goodnight. Then maybe 10 mins later she text messages him and says something about 'i'm in a time of need and you're just beeing an asshole' i'm like OMG!!!

Sooooo all that said he's moving in with me next week. Do I have the right to say break it off completly?! I mean I know he's just trying to be nice because he's a nice guy but I don't know how much more I can take. And how do I say it without him getting mad at me???

You always have the right to break things off if you feel uncomfortable.

Plus his ex sounds like a complete pysco bitch.

Yeah i agree with above, scary or what.

and you should never feel pressured to do what you don't want to, unless of course, it is school
