does he want sex or a commitment?

Here recently ive been kinda texting a guy I went to high school with. He was kinda the shy nerdy kid until he graduated now hes buff an works out twenty four seven. Randomly he will text me wanting to hangout kinda like a date but I feel like im his last resort. I always refuse because I actually wanna get to know him on a certain level just to see if we have similar interests but we hardly ever talk.. also hes been single for two years
