I'm worried and possibly scared.

So, my current LO likes me (at least I fairly certain she does and will be baffled if she doesn't). She has been a LO in the past but things got weird so I kind of forgot about her for a while. I still thought of her on occasion and wanted to talk to her though.

Anyway, I'm trying to say, I don't know if that's all she is to me, a LO. I don't want to start a relationship with her if it's just going to hurt her especially if I know the outcome ahead of time. I think I like her beyond limerence but I don't know how to tell, I don't what's supposed to tell me if I lover her of her just lust for her.

I'm scared of committing to something I know is fake, basically. Not for my own sake, but hers.
