nagseselos sa pinsan ni boyfriend

Problem/Goal: Hello, please don’t judge I just need advice kung paano ‘to maiwasan. sorry if this sounds weird and immature, but I feel a little jealous of my boyfriend’s cousin.

Context: Alam ko naman na selosa akong gf pero hindi ko alam bat pati sa pinsan nya may na feel akong ganun lol. So my boyfriend and I are very open with our social media accounts, and may times na sinesearch/stalk nya lang ‘tong specific pinsan nya na girl may iba rin naman syang pinsan mostly lalake pero di nya naman tinitignan account nila., sa mga babae naman she’s the one who’s closest to his age tapos puro matatanda na and na kwento rin naman nya na sya yung close nya among the rest sa mga pinsan nya, btw si bf living and working sa Vancouver while yung pinsan nya nasa Edmonton. ewan ko bat nagseselos ako minsan pati sa IG nakikita ko nasa search history nya sabi ko sakanya may mga iba ka rin naman pinsan bat hindi mo iniistalk sya lang?

Previous Attempts: I confronted him pabirong sabi nya lang sakin “love pinsan ko yan ganyan kana ba kabaliw sakin”

love na love ko si bf pero i don’t know sobrang weird lang bat nagseselos ako sa pinsan nya pa talaga. lol.
