<human>: So I matched this one girl on Tinder, and things started out well. We chatted for a few days, found a lot in common, and had similar senses of humor, so I decided to go on a date. The date went well, and we had a good time, but (1) she lives too far away to see often, and (2) she's a close relative of one of my sibling's good friends. We both thought that this would work fine, and arranged another date in 2 weeks on Valentine's day. 

After the date, I decided to friend her on Facebook. (Should I have earlier?) Of course she said yes, and after some minor snooping around (ok, Facebook stalking) for a couple of minutes I realized that she's bi. I know this shouldn't be a problem, and I should just continue with the relationship, but for some reason it just feels like the dynamic on my side has changed significantly. One reason of this is because of my family. I was raised in a very conservative Christian home, so I'm pretty sure they won't approve of the relationship if they find out. Secondly, it just feels weird. I know she's into me, but I feel a lot more awkward getting close to her now. I can't explain why, but the feelings are just different now.

She doesn't know that I know yet, so I feel like I have an out at this point. I also feel bad breaking up with her specifically because she's bi, but also because that just feels plain wrong to do something like that. On the other hand, I feel like the feelings of closeness and friendship we had early on are not the same as they once were. I pretty much have 2 weeks to come to a decision, as that is the next time we meet in person (but I also don't want to break up on Valentine's day). I feel incredibly conflicted right now.

Can you summarize the given text in a few sentences?
<bot>: Just started dating a girl, we really clicked, I found out she's bi, and now I can't feel the same way anymore and have no idea what I should do.
