Help I caught feelings for my FWB!!

Me and this guy have been hooking up for awhile and I caught feelings. Both of us agreed we didn’t want anything serious at the start but now I kinda like him. The big issue that I have is that he is on a break with a girl he was talking to over the summer but they never dated. I just don’t know what to do. We also haven’t hooked up in like 2 weeks but we have both been really busy. We had fall break and he’s in season for his sport so he’s not here that much but am I overthinking it?I don’t want to seem like one of “those girls” if you know what I mean.
