How do I get rid of this girl?
So I’ve been talking to this guy for about 7 months. We are not together. I really like this guy and I know he likes me as well. But there is one problem... his ex girl friend. He lives with her and his friend. (For your information)- They do not do anything together. I know for a fact. All he sees her as is a friend and that's it. He wants to kick her out but if he does that, she won’t have anywhere to go.
She keeps saying that she’s going to have kids with him. Mind you, they have not done anything for that to happen. She also said that if he makes her leave, then she is going to kill herself and even if he does make her leave, she will make sure that he is with her.
I don't understand this girl. I think she is a little messed up in the head but I don't know. She honestly thinks they are together but they’re not. I see this girl all the time and she sees me with him. I don't know what to do. Sometimes I just want to give up on this, but I really like this guy. What should I do?
