Hello palsera, I know from your other posts that you've had a crush on this lady for some time. And I've read that you saw on her Facebook that she is heterosexual. You are looking for romance with a lady that would probably feel extremely uncomfortable and possibly horrified at the thought of being romantic with someone of the same sex.

I'm sorry, yes you can ask her but I think you are going to be disappointed. There will be plenty people who would want a relationship with you, you will find true love in the future but not with this lady. Take care.
