All Bigs must DIE!!!!

Ok. I'm tired. Very very tired. I now work two jobs, I haven't had a day off (at ALL) in 9 days. I'm physically and emotionally exhausted. Sometimes all I want is just a little support. *sigh* Ok, here's the story. Big has been living with me for almost a year now. We started off as fuck buddies, then I fell for him- because I'm stupid -and we dated for a forgotten amount of time. Well, (and remember, I'm stupid) I broke up with him, thinking it would be a good idea to get back together with my ex-fiance. Well, that flopped within a week and I go crawling back to him. Back to MY house (I moved in with a friend to give him time to get out) Well, so I get home and he is ... Emotionally detatched at best. But- he still acts all sweet and boyfriend-y, but there's no "spoken" commitment. Well, we have a pretty decent few months together and it's decided that he's going to move out, but we'll still see each other -- more or less. He never verbalized that he wanted to see other people and still- there's that boyfriend-y attitude. Well, still - I'm stupid - last April I ask him to stay with me until the end of August because I took a student position at a nursing home which pays a little more than minimum wage. I asked him to stay to help with the bills until I start making that big CNT money (yeah, right). So that leads me to today. Today being the 9th day I've worked without a break. Big's 13-year old brother had been staying with us for a couple of weeks and basically my house is a disaster area. I don't have time to clean up after Big and his bratty little brother (both of whom are complete slobs, btw) so today- I snap. I scream, I throw away Magic cards (which are strewn EVERYWHERE!!!)- and all of the sudden Big wants to help me clean. I'm sorry but he's had two weeks to tidy up if he so chose. As if that wasn't enough, today being the fourth of July he's going to his dad's for a bbq. That's fine and all, but while he's gone, I sit down at the computer to check my Yahoo! Mail. Well, I bring up the mail.yahoo.com site and Big is still logged in. The first thing I see are websites confirming his enrollment in www.adultfriendfinder.com. For those who don't know, Adult Friend Finder is a site where people meet people to fuck. In a nutshell. No, not literally fuck in an nutshell I mean.. ah, forget it. So, Big and I aren't "together" ... do I still have a right to be furious?
