Replacement Addiction

I suck. It seems that the instant my relationship is in trouble I wind up with another guy in the picture. It has happened before, and it will happen again. Every time it happens I gain a bit more control over the situation. This time I didn't wind up really doing anything with the replacement guy, but I know exactly why he is in the picture. I was at a party on Thursday night which was mildly entertaining, but my ex-unboyfriend was there (it was a strange relationship). Considering all the drama surrounding Chuck right now, I completely neglected to act like I was in a relationship once a few drinks were in my system. I vaguely remember the night, but I do know that I was extra flirty with this new guy. Saturday night I told him the situation (telling Chuck is completely out of the question). Thankfully he was fine with the whole thing and we were able to get past it and still be friends. I know, however, that the minute I am single he will expect that to change. I honestly don't know if I would actually persue anything with this new guy, even if I was single. Strangely Chuck said that Thursday night he couldn't sleep. He felt worried that he would lose me (which is a just a matter of time at this point). I think he sensed that things are changing rapidly, and the tide is turning against him. Pretty soon my patience will be completely gone, and this other guy is just an indication that it won't be long.
