<human>: My girlfriend (age 20, I'm 23) has been different lately: whereas she used to be far more enthusiastic about being physically intimate, she now pushes me away when I try to touch her in a non-platonic way.

It's tough for me to talk about this with her, but I believe this is because of her birth control pills. She's on OTC, which is notorious for depressing libido, and uses it to skip her period, which, though safe nowadays, accelerates the rate at which the hormones affect the body and mind. Even so, it's not a subject guys are really allowed to discuss, isn't it?

She's not been very communicative about the issue, which is the hardest part of this. When I asked about the recent turn to celibacy, she admitted she just stopped liking sex. I asked whether she thought that might be the birth control. She said she doesn't care whether it is because she's fine not caring about sex, and added that I seem to care more about sex than how she feels. I personally think this is an unfair criticism: is she saying not having sex is more important than how I feel?

I finally asked whether she'd consider switching birth control. She said she'd look into it in two months when she sees her doctor again. Two months without feeling intimate with my love? Two months of having to constantly worry how I touch her when were close? Two more months of these hormones wrecking her system? But I can't discuss it further; she is obviously uncomfortable bringing it up. Again, it's the lack of communication that really kills: is she uncomfortable talking about that issue, or is she uncomfortable talking about it with me?

Well, its all so sudden. I've been with her for about nine months and she just recently started acting like this out of the blue. Is there any way to approach her about this? Should I just end it now?

Give me a shortened version of the text
<bot>: girlfriend has become more and more distant ever since she started taking birth control, now says she doesn't want to have sex with me and pushes me away when I try to be intimate, and refuses to discuss the issue.
