<human>: Summarize the given text in a few sentences.

My girlfriend just told me she is bi and prefers women. I am not homophobic and I am happy she told me, but I am definitely feeling insecure. I actually feel good about the idea that she chose me over women, but the truth is she didn't really choose. 

She comes from a strict catholic family and she really honors their beliefs even if she doesn't agree with them. Therefore, even though she prefers women, she has never made an attempt to date them or even hook up with them. She likes men too, she just avoids women because she doesn't believe she has another choice. Should I feel insecure about this?
<bot>: I feel like I'm just the next best thing and that she doesn't actually want me, I'm just the best that she can get.
