I think my friend is stalking me? Help? (kinda long)?

[Chantelle ♡]

Okay well he is a close friend of mine, he is gay. I have known him since freshman yea of high school we are now seniors, but we never really started to hang out a lot until the beginning of summer. Anyways, I seriously think he is stalking me. He has a facebook, but for some reason he's constantly deactivated it. I swear he only goes on it to look at my profile & then he deletes it again. It happened twice today, I wrote a status & he assumed it was about him & it wasn't. I'm like what are you talking about? He said "on facebook" & then I was like okay weird cause its deactivated.. So then a few minutes ago he texts me asking if we had homework for the 2 classes we had together. I wrote back no, but if we did I didn't do any. & then he replies with well what homework did you do? & I said none, cause I thought he meant from the 2 classes & he said "but facebook o.O" seriously this just creeped me out, I had a picture on facebook I uploaded earlier of my cat laying all over my homework, & he went on facebook, to my profile, looked, & deactivated his account again. I know this because he isn't on my friends list, only when its activated obviously. But really this is so sketchy & I don't know if I'm overreacting. There are some other things too like every single day he wants to drive me home from school & he stays 'til like 9 o'clock. Like I hae other friends to hang out with, & I'm not gonna be rude & be like LEAVE lol. But yeah & he always texts me asking what I'm doing or where I am. I see him every day before school because he picks me up & drives us. We have 2 classes together & lunch. Then he drives me home & stays FOREVER!!! It's just starting to get annoying & creepy I don't know what to do. He is gay & has a boyfriend so I don't think a "crush" could be it. Help me am I overreacting or is this just really creepy!? Help me??
