i have limerence for a girl i had a crush on in highschool, and im currently in a relationship going on 2.5 years. she was my bestfriend and we had this weird romantic 'relationship' but never dated, never talked about it and basically pretended there was nothing going on. i know it wasnt one sided because our friends told me she felt the same. however, a few months after this 'situationship' started, she suddenly left our friend group. she didnt talk to me, we never hung out again and then the next year i moved to another state. i hadnt thought about this girl for like 5 fucking years - ive graduated, dated my ex gf and met my current bf in that time. but since moving back to the state she lives in, i think about her all the time. i create scenarios in my head. i stalk her socials. i engage with media she likes hoping she'll notice. i want to text her or see her in public. ive even started to dream about her. this obsession is starting to ruin my relationship and idk what to do.
