Well, I must say you have been given a LOT of advice. The post by #61756 was uncalled for and was anything BUT support.
The other advice you received was OK, but I would think twice about bringing women to your apartment. A couple of the posts were GREAT, so listen to Trapper and Kathryn!
The only thing I would add is this.....Because I am in property management and have had many dealings with roommate situations, let me tell you this......IT IS HARD TO LIVE WITH SOMEONE. Kevin, you may think you are the most easy going human being to be with, but I bet your roommate feels that way, too. But, when two human beings come together as roommates, something usually goes wrong and there's no one thing you can put your finger on. I have had roommates come to me saying things like...."My roommate eats all MY food, My roommate is a slob, My roommate gives me no space...." I could go on and on, but you get the picture.
Now, I am not saying this is what is happening in your situation, but what you are describing is normal. It is no reflection on you whatsoever!
Oh, and if this roommate does not work out, next time you get a roommate, establish "the rules" before you become roommates. I sincerely hope this works out, but over the years, I have seen best friends no longer speak once they lived together. I wish I could explain what happens, but something is triggered with roommate situations. If you can afford a one bedroom, then live by yourself.
I hope I haven't bummed you more. Just enjoy today and have a Happy Thanksgiving.
