do feelings ever end?????

hey! i havent posted or even been on this app for ages but i need some advice.

(please excuse the grammar, it’s late and i havent got auto capitalisation/ autocorrect on)

so about a year and a half ago, i was talking to a guy who lives about 3 hours away. we have never met, but we started talking and me, being naive, i caught feelings hard. he was only there for one thing, but i really liked him until he left me for someone who lived near him and they dated for around a year. but recently he’s been getting in touch again, he’s come back twice then left me for his ex and each time it just hurt again. he’s left me three times for the same girl now. but i cant seem to shake my feelings for him, its like an addiction, whenever he gets in touch all i can think about is talking to him. i wont go into everything but basically he still likes his ex and i’m obviously second choice since she lives closer even though he says he likes me and is only talking to me.

anyway, i cut it off today, after speaking to him multiple times about how i cant be second choice and how i cant trust him. but even then it hurts so bad, and i end up barely leaving my bed for a week.

my question really is: do feelings like this ever go away?

ive had a boyfriend between us talking and i still feel more for this guy than i did for my boyfriend

is it love? maybe my first love that i can’t fulfill?

does anyone else have this problem?
