this "take a chance" business isn't all its cracked up to be

[HotDamnImAPhiMu]

So I've been hanging out with this guy for a couple months now, and while we're not dating, we do all the things dating couples do. Neither of us is seeing anyone else, we go out to dinner together, and nobody's surprised to see us holding hands anymore.

He's brought up actually beginning a relationship lately -- referring to me as his girlfriend, getting more serious in general, I suppose. But I was hesitant, for a couple of reasons. Intially I thought he still had some ex-girlfriend issues. I don't think that anymore, but I moved back home a couple weeks ago, and starting a relationship living 90 miles apart probably isn't topping the 100 Easiest Ways To Start A Successful Relationship list.

We got into an awful, awful arguement a couple days ago that kind of snowballed into three straight days of arguing. We finally set things straight last night, but I'm anxious -- this makes me wonder if it's a huge, huge sign that THIS IS A BAD PLAN.

I really like this guy (at the risk of sounding thirteen) and love being around him. I'm not trying to marry him, but I'm also not trying to throw myself wholeheartedly into a semi-long-distance relationship that's doomed from the start.

He talks a good game. He's made it clear he has strong feelings for me, "good intentions" (come on, admit it, that's cute) and thinks the arguing is the result of learning how to deal with each other (i.e., not just butting heads.) But I can't get over the fact that we just had a three day drawn out argument and we're not even DATING yet.

I can't figure out if this is something I need to stop thinking about and just take a chance on, or if this is something I'll look back on in half a month and be like, Good LORD, what was I THINKING?!?!

thoughts?
