Obsession? Who knows?

I keep fantasizing about her, it’s so odd, I think of her a lot. We are friends..? No, best friends if she still thinks of me like that. But uh after the argument we had a year ago our relationship is kinda strained or cold, dry...the thing is I think of her each day. I talk to her almost everyday and she writes stories of our friends and it’s fun. She uses me a lot as her protagonist often and our friends being the side characters. I’ve often thought of making her only talk to me and keep her from making more friends. She’s an introvert though, that parts a bit easy. I get jealous when ever she pays attention to others, when she laughs with others. If I don’t make her laugh or smile I’ll immediately think about how stupid or worthless I am. She’s really pretty, and I think I’d be happy if she was my lover or at least someone I can call mine. I don’t know but I’m pretty sure this is an obsession...I don’t want this though, I’m so tired of thinking of her every day. I hate how she can easily control my thoughts with a small action. Sometimes I wish I haven’t met her, but some of my precious moments are with her...
Should I cut off contact with her??

Anyways can we agree on all of lady Gaga’s songs are iconic(▰˘◡˘▰)
