Cant stand it anymore

So I am moving out to a new place this week. I found a girl that I am going to be rooming with and she seems pretty awesome. We met a few times and get along great. We are trying to fill up the third bedroom. She found another girl to take it a few days ago. I just met her today and she's nice, conservative, laid back and we were all able to keep the convos going. We all actually had a very fun night tonight. My b/f on the other hand thinks other wise. He made me find out her last name so that he could look at her profile on facebook. He stated that she seemed "stuck-up" and can be the type to get the other girl to gain up on me. I seriously don't need this now, moving is stressful as it is. He kept saying that he got a bad vibe from her. All just by looking at her profile. Stating that she complains a lot in statuses and that her taste in hobbies and music is awful. And then he goes off and posts ads for me! Saying that I can find someone better. I am sick of his controlling attitude and his cockiness of him thinking he knows everything. He hasn't even met her yet. This is driving me insane. and with him over blowing my text messages. uhg.
