I think instead of jumping straight to seperating, she should call him over to germany away from family. He will need loli to help him settle, she can sort of show him the way she lives her life and how to be happy and not so materialisitc at the same time.
I know it sounds harsh but if he depends on loli for a while she will have more control over the relationship and they can maybe build and bond and maybe he will change. ** If not then kick him right back to pakistan! **
Plus a baby needs its father so maybe it is time for him to come over.
yup if all else fails then that seems like the best option.. The time spent on him jsut about getting citizenship could be the time u take to understand his true intentions towards you. If you dont see change then do what the girls suggested.. boot the fool
