Should I break up with her?

Depends, if she is filming her self for her own use or for you, then I dont think there is a problem with it. To be really honest, it's easier said than done and I would be really reluctant if my girl asked me if she can do that. I would be a little resistant but I wouldnt mind long as its just for us and as long as it's protected so any third person cant get a hold of it. I would be more reluctant in terms of it getting in the wrong hands but besides that it's not a major thing to break up over.

However, if you feel like that is not your thing,, or you find that completely unacceptable, then talk to her before breaking up...you have been together for 2 years and it's better to talk it out. If you feel that you couldnt reach a consensus that you both agreed on, then it's up to you...

what do you mean by "she was going to film herself touching herself"? like film herself and post it on a porn site or skype you while doing it? and "decent" girls don't need to be saints in the bedroom. in fact if they were, you'd probably get bored pretty quickly. Maybe you're not old enough to understand, but there's a big difference between a girl acting this way in public and acting this way in private. If it's only for you, then I dont understand why it's such a big deal. She wants to turn you on, to be sexy for you. Talk to her before you throw away a 2 year relationship over something as stupid as this.

She's disrespecting herself, she probably trying to see how your going to react to her comment she made. Maybe she wants out of the relationship. Or Maybe it's a good idea to break up with her. Or maybe she just wants to go deeper in the relationship. You both need to be on the same level. Go with what you feel is right. Is a one time thing going to make you want to break up with her or should u just tell her how you feel and go with that?

I hope I helped:)
