<human>: Can you give me the gist of the text in a nutshell?

I know my gf from work, and had a one night stand with her 3 years ago.  We are now 2 years together, and I love her.  We did sex right from the start, and the sex is really great. 

But, since last year she has been less inspired and more evasive to do sex . I didn´t understand it because she likes to say how sex is amazing for her, but I though it was just the passion dimming.  She went through depression, and during that time she was rarely in the mood for sex, and I respect it. She is getting better just now and went back to church, but as a catholic she can´t have sex before wedding.

When we met, she wasn´t an active catholic, and appeared to be even less religious than I am. That changed, and I kind of blame on her  sister for it. (Her sister is a very very very religious person). I have no problem with her religion, apart from the sex.

I must say I am pretty angry about this. I really don´t want to end this relationship, and if I want it we will have sex just because I know to turn her on beyond her defenses. But I don´t want guilty sex, I want her to ignore this rule like everyone else does. And I don´t see myself marrying in the next 2 years.

That said, I think that the period of not having sex so far is making us more horny which is actually good. Maybe I am just finding a way to get a positive aspect on this.

To me seems like I have no choice, I can give in and agree to not have sex. Or I can finish this relationship.  Do you guys see any way out ?

Sorry for any bad English, I'm not a native speaker.
<bot>: gf went back to religion, don´t want sex until marriage. I don´t want to marry in the near future, and I love her. Any options ?
