Woah, what?

First off, you've been dating this girl long distance for 2 months. It's fine to say "I love you" and all if you feel that way, but the dramatic BS about "only loving her for sex" is absolutely ridiculous. Love is based on trust and respect, if she doesn't trust you enough to love her for who she is, then she doesn't love you man.

Secondly, why are you still referring to this man as your best friend when he completely violated your girlfriend's privacy and broke your trust? That would be means to terminate the friendship for me and absolutely is not okay. That's very invasive of him and will probably leave her feeling very vulnerable and exposed, possibly not even wanting to be sexual.

It's been like, a week dude, and you're emotionally manipulating her for not wanting to be as sexual (because her privacy was invaded and you didn't seem to take it very seriously) by crying and insinuating she doesn't love you as much as she used to. Dude, whaaat? That's ridiculous and shows how inexperienced, and frankly immature, both of you are being.

As selfish as it is, its bothering me that I no longer have those revealing photos and videos. Ive also sent her some and when I did so, I did it in good faith. Even if what happened to her happened to me I wouldnt tell her to delete them.

That's really dismissive of her feelings and shitty. It doesn't matter if you wouldn't mind someone seeing your small, wrinkly ballsack. She clearly has an issue with your creepy friend having access to something she sent you in confidence and privacy. She trusted you and you broke it by not securing her trust well enough and by allowing your friend to have access to this content easy enough to sent it to himself.

Very inconsiderate, regarding the circumstances, and you have the audacity to be upset at her for not wanting to send you more?

...And you're long distance as well?

Dude. You need to grow up a little, start being more respectful and considerate, and just..I don't even know what to say to you because of how oblivious and inexperienced you seem. I hope that you're able to see how you could have better reacted in this situation and you need to stop blaming/being upset at your girlfriend because she did literally nothing wrong and her actions now following are a direct result of your "friend's" actions and your blatant inconsideration for her feelings.
