Is she possessed by the devil?

a friend of mine is working several jobs to support her family while the boyfriend pretends to look for work and quits job after job. after receiving unemployment for years, he is sitting at home smoking 2 packs a day and plays video games. my friend is a very smart women that no one can really take her for fool except this guy. is she possessed by the devil? she is willingly to let him take advantage. she looks like a complete fool or worse yet, a women possessed by the devil? what do you think? i feel helpless when she won't listen to me, she is ruining her own life and gets defensive when I comment on her situation. I just want a better like for her, if she is not willing to help herself then I guess no one can help her.
