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

I've known this girl for about 6-ish months, but I only really started getting to know her around the end of our last semester of high school before summer break - about 3 of those months - (we'll both be seniors next fall). I've been making efforts to try hanging out with her, but the plans keep falling through. Most of the time it's because of legitimate conflicts with schedules/prior commitments/etc., but other times I feel like she just doesn't really care or isn't interested. She has said that we will definitely meet up at some point over break, but I just don't know how to go about confessing my feelings in a decent situation without putting too much pressure on her or myself. So I guess really this is a few questions in one.
<bot>: I have feelings for this girl, and I'd like to know how I can gauge her interest levels and potentially start a relationship.
