The girl I've been seeing is also talking to another guy

Alright, so this is kind of a 2 sided issue.

I've been seeing this girl for about a month now. We text everyday, fall asleep on the phone together every couple days, flirt and kiss all the time. We basically act as if we are a couple (excluding sex). We go out at least 3 times a week. From fancy dates, to the beach, to each others' houses and occasionally we even workout together. I really like her and it seems like she feels the same way.

However, I recently discovered that she is also talking to another guy. I don't know how serious they are talking though. She also doesn't know that I know and hasn't told me. Is that bad? She never talks about any other guys when we're together and ignores all her calls and texts. I haven't confronted her about it because 1) we're not boyfriend & girlfriend nor have I even asked to be exclusive 2) I don't know how to confront her in this situation. Should I even confront her since we're not exclusive?

The reason I haven't asked her to be my girlfriend or be exclusive is because she is leaving to a different college about 300mi away (I would get to see her at least one weekend a month). I've never been in a long distance relationship before and I don't know how to feel about it. I want to see how things between us will be with the distance first before I try to solidify anything. We really haven't had a talk about what's going to happen to us when she leaves, but she has told me multiple times that distance doesn't matter to her and she wants to keep things going how they are.

Back to the first problem though. How do I know that I'm winning her heart? How do I know that she's not as involved with the other guy? Should I just be straight up with her and what I want?

I would really appreciate some serious, solid advice. I know this is long, but I've searched and searched and there really isn't any other situation like this up anywhere else on the internet.
