Questions

So there's a guy at my kickboxing class that I partnered up with about two months ago when I was pretty new to it. He was very nice and helpful and we talked while we were partnered together, like I asked about his career etc. And we generally got on well.
Since that I have said hello and bye to him when we are both at training and I smile at his across the room etc but I haven't had a chance to partner him again or chat properly because I am pretty shy and I think he seems to be too.
Anyway I haven't seen him at training for a couple of weeks but he sent me a friend request on Facebook a couple of days ago (I obviously accepted) and I guess I'm wondering if it means anything? I know it's a silly question, go easy on me, I don't know much about guys but I obviously do fancy him and I'm sure he's seen me checking him out in class 😅😯 but yea just interested if guys will randomly friend girls they know or if this might mean I have a chance!
