okay.. new girl.. again with a bf. sorry guys i know this is stupid shit.

anyway, ive been talking to this girl with a bf. i know shes into me, but she won't do anything cos of her BF. shes told her friends she likes me blahblah. anyway, i've actually become emotionally attached to her so i want to kind of cut it off but i want to explain it to her so shes aware a bit.

any ways you guys can think of phrasing this?
