Am I a stalker??

After my first rollercoaster relationship we decided to call it quits and I accepted it and got on with my life. I see him all around campus and sometimes he talks to me. Before talking to me he unfriended me on Facebook so I just got on with my life. However afterwards, a couple of days later, I accidentally like one of his tweets one evening, and he deactivated the account. And I only realised this after two or so months. Then on his birthday weekend I on two occasions get off the bus early from uni to my house and his area is along the way to my place. Then later on campus I'm getting a bus from the gym and realise that I MIGHT see him and understand what I'm doing is not okay so I move away. I've since avoided my impulses to see him.

I mean, it was intentional that I got off the bus earlier than usual and I knew that I have to walk past his area. I think I was hoping to see him on all of those occasions. I was going home but I also was at that bus stop hoping to see him. Another occasion went to the bar with my friend because he sometimes goes there with his friends. Not cool, I know.

The second time I got off the bus top early and when I waited it’s like I ENJOYED doing those things?? I hate myself for it who the fuck am I? 

What if he saw me? What if I ruined his day?I feel SO GUILTY. I feel like dying. I know what I did isn’t okay, but I just need some help. I’m sick to my stomach. I'd appreciate your input as my friends, therapist and family keep on saying I'm NOT a stalker but I just can't get out of this spiral.

tl;dr am i a creepy stalker
