<human>: Can you succinctly summarize the text in 1-3 sentences?

Background, me and my fiance have been together not too long (only a year and a few months) but he proposed this summer and now we're planning the wedding for summer of 2014. Well there is one problem. His mother drives me nuts. She does not like me, does not like our relationship, and stays at our apartment about once a week. I can't take her spending time here if she is going to continue disliking me and the relationship I have with her son. But I feel awful asking my fiance to tell her she isn't welcome here anymore. But it is getting to a point where it is making me physically ill and making me wonder if he will go through with the wedding or not. I'm mostly just scared and annoyed. And now it appears she will be ruining our late Valentines date tomorrow. I've been planning it for 2 weeks and if she messes it up I will probably curl up into a ball and cry for 3 days. So what am I supposed to do at this point?
<bot>: My fiances mom hates me, hates our relationship, and I'm sick of dealing with her. What on hell should I do about this problem?
