Parasocial relationship

Have you guys ever had a parasocial relationship with others before? I am in this situation now, and i feel like shit.

But the thing is, my oshi always interact with opposite gender and i actually feel happy about it and i even ship him with them sometimes. But for the first time in 4 years i found a certain person annoying and i don't want her to be close to him. I try to watch this person and change my feelings towards her but it just get worst. I can't stand hearing her high pitch voice cuz it feels like they are acting cute on purpose to get his attention. I wouldn't be suprise if this true cuz my oshi is actually popular and i see countless of ppl got popular bc they interact with him.

In the end i cried, not bc i feel jealous but i hate how i feel this way. It sucks that my heart actually hurt sm when i see them interact. I don't want to feel this way and i don't want to hate them. It's good that after 2 days i will never see them talk again tho.

So anyone who experience this feelings, how do you get over it? (￣ε(#￣)Σ
