She sends me messages saying he has hooked up with other girls (which I know are complete lies and she is just crazy) and I deleted her as a friend on Facebook when this first started happening but still she messages me and tries to add me as a friend again. Not to mention the fact that she calls my boyfriend at least 3 times a day.
He never answers because he is done with her but she still wants him back. He always shows me the texts she sends him, which are like six pages long, just saying that they belong together and she loves him and please won't he take her back. Sometimes he responds saying no he is done, but sometimes he just ignores her.
A few times she has even shown up at our school on a "college visit" which is beyond creepy. I would have no problem with him keeping in contact with her if it was purely just friendly (instead of her constantly trying to convince him to leave me), but it seems unlikely that she will be happy with just being friends with him.
