Is it wrong if I have sex with my neighbor?

She's been upset lately cuz her parents are getting a divorce and she said she needs to feel comforted. So I was consoling her and she started to make out with me and strip down. Then herbmom got hone. Weve beren friends for 8 years and I don't wanna feel like in taking advantage of her emotional state. Were both 17 and she and I have done ish before, just not sex.
