<human>: Summarize the given text in a few sentences.

This guy [26] who's in my [F24] graduate program and I have been hardcore flirting for the last few months. We hadn't talked much online or texted, but in person I could often feel him looking at  me and we'd flirt a lot when given the chance. We finally hung out alone for the first time this past Friday night (watched a movie at his place) and ended up talking for hours and intensely making out for a good 20+ minutes. We get along really well and both feel really comfortable with each other and agreed to hang out again Saturday night, which he called off from being too tired after his long day. I tried to make plans with him yesterday which he happily agreed to but then had to cancel again. 

I don't know him well enough to know if he's actually blowing me off or if he's just a little flaky, so based on the info I've provided can anyone give me a little insight? At this point I'm waiting for him to ask me to hang out since I've tried twice to no avail. I like this guy a lot and although I know he likes me I'm not sure to what degree. I'm not even looking for us to go full-relationship as we'll be in different states for the summer starting in a few weeks, I just want to spend time with him because I enjoy his company! However, I also don't want to pester and pester and pester him.
<bot>: Finally hung out/made out with guy I've been flirting with for months. Both had a great time, now he keeps canceling plans I try to make with him. What's the deal?
