How to tell if she has a boyfriend?

Anonymous
so me and this girl have been friends for a while, then we sort of fell out of contact for a little while. she started to hang out with another guy (which I had no problem with). but now she seems interested (she was asking if we could hang out), but I don't know if she's with that guy, or not? or what?

so my questions are:

1) is she with that guy?

2) is it reasonable to think she likes me?

thanks!
