rocd is bad over my gf's sexuality

i'm soooooooooo insecure over my girlfriend's bisexuality
i'm a girl and so is she, she's told me so many times she prefers girls but my mind obsesses until the point i'm in serious anger and pain over her being bi :[
idk why? :[ can someone help me out? it's not that i don't wanna accept it, it's just SO hard when i'm so insecure over it to the point i'm so envious and hateful towards guys she finds attractive.

i get mad over everything, to me it seems like she's a fan of more males than females who are famous, she even had a male as her twitter header image and he was "manly" so i worry about how can bi people like both feminine and manly? :[ so i keep obsessing and trying to tell myself good thoughts, then i feel okay again but then something else comes up, it's a repetitive cycle of what ifs :[ she's only been with guys before me too, so i'm even more insecure about if i can match up to them. i constantly keep reassurance seeking by asking her questions about what she would do sexually with a guy...i just don't know how to stop feeling so angry and hurt by all of this, every time i think about how she likes guys too i feel a huge anger and pain inside of me. it won't stop

I'm going to copy this into the relationships forum. it will be in this forum and the other one.

I have jealousy and insecurity issues with my gf too (although i am a male and she is straight) so although i can't help you as i haven't got over my own issues, I can at least tell you that 99.999999999999999999% of the time you're making it up in your head.

I'm a horribly jealous person, although I've finally gotten it calmed down a lot. I'm still insecure sometimes, but I learned that the only way to cope with it was to let it go. Our partners are with us for a reason, and as scary as this reality is, if we keep pushing our jealous thoughts onto them, they're going to start keeping it to themselves to avoid the trouble.

I don't think I'm the best person to being giving this advice, but as someone who's learning that they're bi, I don't even compare the two, let alone compare women to my boyfriend. I don't think it's any different than being straight truthfully.

Believe me though, I understand your pain so well. It's been a curse on me for nearly 2 years...it's hard, and it takes a lot of persistence and pain, but I promise if you start trying to let it go, you will notice it not hurting so bad.

i'm going through terrible motions of anger over this right now i feel like an evil person but i just can't help it.

i feel envy, disgust, hatred, closed minded as to how she can even like guys too, everything is just tugging onto my anger so badly, i know it's not important what her sexuality is because she loves me, it's not an issue. so why am i so hung up on being angry and disgusted at how she can like men too? i just can't stand it...

i have a thousand things running through my head each day and they constantly bother me
i always think about how she showed me a pic of a guy's abs
how she enjoys manliness and abs
her words when she told me she'd have sex with a man if she was with him
how she's had past boyfriends and it makes me feel sick she obviously enjoyed intimacy
I JUST CAN'T RID THESE THOUGHTS AND THEY HURT SO MUCH I'M GOING INSANE.

she's dedicated to me, she'd never be unfaithful, she adores me more than anything, she gives me so much reassurance that she wants me and not a guy (but once she said it would be the same if i was a guy, i mean how am i supposed to feel that she's careless about my gender? she doesn't understand how it hurts that she doesn't care if i was a guy or girl, but it does.) anyway she always tells me that she prefers girls and she'd even not do certain things sexually with guys but i honestly can't help but think of it as lies. but the fact that if i was a guy or if she'd never met me and met another guy, it'd be exactly the same with him as it is with me, TORTURES ME. i think about all the things she'd do the same with a guy like she does with me and it hurts. is there anything i can do?
