My ex-boyfriend won't leave my apartment. He does not pay any bills or household expenses. We broke up over 1 month ago and he said he is not leaving until he gets ready. Can't I do something about this? I am trying to evict him. I cannot break my lease and move elsewhere. I am trying to weigh my options because I could move to another apartment in the same complex but does this mean that he has to come too? I thought about changing the locks. Is changing the locks legal when there is another tenant? I would also like to know if evicting another tenant is costly? I really want him out but he knows his rights. What can I do?
