<human>: Can you succinctly summarize the text in 1-3 sentences?

So 2 years ago, I became really close friends with a girl on my floor in college. Over time, we started acting like a couple when we're together. So we'd just have little actions/interactions that are usually associate with a loving couple: hold/touch hands a lot (although that's a tendency of mine w/ girls), she naturally leans towards me when we stand together, she'd stare at me...w/ a curiousity in her eyes, etc. It's hard to explain but basically, we've both acknowledged that we act this way and many people have asked us individually if we're dating (including our parents).

Now, for a year and a half, I didn't really think much of it. It was comfortable and just how we acted. But in March, I started to think more and more about what it'd be like if we started legitimately dating. Now, I can't stop thinking about it but I don't actually know if I like her or just the idea of a relationship with her. 

What do you suggest I do to figure this out w/o compromising the friendship? 

Also, as a sidenote, I read through this subreddit and couldn't help but think that she likes me. We're close, she's excited to introduce me to her friends and apparently her parents have asked why we're not dating yet (and she shares a lot with her parents). However, she doesn't like it when her friends post comments that suggest we're dating on fb pics of us together (and makes a strong effort to get her friends to delete the comments), she should be way out of my league by any convention and we don't actually talk much once we're not together physically (no phone, text, skype). What do you guys think?
<bot>: Friends that act like more than friends when together. Are we more than friends or just friends? Also, I feel this is something a teenage girl would write...so sorry about that...
