I feel like i’m just insecure and overthinking things

[short token]

Hey, i’m 16, im in a new relationship, it’s our one month tmr, i need advice, real peoples opinions, my girlfriend, she has this best friend, and it was okay to me at first but then i learnt more about their past, my girlfriend once a couple years ago used to like him, and i know last year they kissed at a party, and in a recent argument when i was talking about it she said that if he was straight and not in a relationship she would have been with him, i have tried to make peace with it as she treats him as her “little brother” and they are best friends or whatever, but it hurts a bit, and i know im just a kid and i have a long life ahead of me to find other people, but i really want this one to work.

If he is gay , then there is no problems.
Even iv he was straight

1-2 friends aren't that big of a problem

Not everyone has the dedication to remove all opposite gender friendships

I am sire you must have that too. Meaning friends that are girls

i know he’s gay and that nothing will happen, it just scratches the back of my head constantly, and i don’t expect her to get rid of him, hes a good friend, its just me always overthinking stuff and being sensitive, and also tbh i dont really have friends, i just have my girlfriend and some people i talk to when on shift at work

So just let it be.

It's also about preference also.

Like some people just don't like it.
So they themselves don't keep any opposite gender friends.

In that case just seek a partner who has similar believes rather than be in a relationship with someone who keeps opposite gender friends

The line between dislike and insecurity , I think is pretty blurry
