My friend was having a little get together over at his house and had invited his friend from 1st grade over as well as our usual group of friends. As the night went on I developed a bit of a fancy for this guy. He was really nice, good sense of humor, was cute, etc etc. At around 10:30 we all decided to go to the park and he said he'd also go even though he had to work the graveyard shift at his work starting at 11. Anyway, we all drove and met up at the park and were playing around. I was sticking by my friend and noticed that whereever we went he would kind of follow us over, he pushed me on the swing, no big deal at all though. We ended up being there until like 11:15 ish and he kept bringing up going to work but he kept staying. We walked to the store to get some drinks and he was kind of sticking with me behind the rest of our crew, offering to carry me twice when I was complaining that my feet hurt but I declined. He said he was going to drive to work after we got back to where our cars were parked but then he ended up driving back to the house with us. Mostly everyone left from the park. He claimed to have misplaced his phone at the house so that's why he came back. ANYWAY, we were walking around and hanging out and he was lifting me up and stuff playfully. He ended up leaving after that at around 12. After he left my friend who has known him since 1st grade was like "omggg he totally likes you, blah blah blah." and I just kind of played dumb or whatever. Then he went on to say that he gets kind of obsessive over girls, like once they are in his head he can't get them out, etc etc. This guy kind of exaggerates things though so I don't know. I mean like he definitely was touchy feely, kept talking about leaving for work but never doing it + following us back to the house when he said he was for sure leaving, and then also talking with me the whole time. I was wondering if it sounds like he has any interest in me at all. He has a girlfriend which I knew of, but it sounds like they are kind of rocky, but she is living with him. He is 18 btw and so am I.
If it does sound like he likes me how should I go about trying to talk to him again?? Sorry this is so long and sorry that I sound so naive, but I need input. THANK YOU.
