Additionally, if you were nuts about Kaysie, you wouldn't have f*** buddies waiting in the wings. I think Take2 is really spot on that right now, you're not ready to give up the single life but you want the advantages of the coupled life. So break up with Kaysie, let her go find someone who wants to give her what she wants (a committed relationship), and enjoy your singleness. And I think when you're ready/find someone you're really into, you won't be running into the problems of temptation that you are with Kaysie.
Haha, this made me laugh. You are basically saying, "Dave, you're not an asshole, but you are an asshole." OP is trying to convince us that he's not a douchebag, but in reality he is a douchebag. Don't kiss up to him. You know he's an asshole and so does the rest of the forum.
I will do my best to reply with an educated, humble and honest answer. Ultimately, it is up to you whether you want to listen to my advice or ignore it completely. Sometimes, my advice may be wrong; occasionally, it will be right. Regardless, I want to do my best to give people answers they are seeking.
