I've been seeing this girl for 3 months. We aren't official because she says she wants to work on somethings and she wants to make sure the relationship will last for the long haul. I've been patient with her and haven't been pushing the issue. Recently she became friends with her ex on fb. They were together for 4.5 years, engaged, and she ended it this past august. He has/had drug problems. No job. No car no license. She psid for everything. They tried to make things work in October to no avail. First should I be worried she won't commit and second should I worry about something happening with the ex
