Hmm it really is a tough situation. She got herself into some serious mess. The easiest way out for her will be an abortion, especially when the father is not supportive. She still has time for that. Abortion after the first trimester can cause serious medical complications, and is very challenging emotionally and morally.
However, if she is willing to make a lifetime commitment of bringing a child into this world and raising him/her on her own, then all power to her. Ask her to put emotions aside and think very straight. Is she ready to become a single parent in 7 months? Raising a child is no monkey business, it's hard work. And there is no turning back after the baby is born.
