How To Get Your Ex Back!!!

My girlfriend of six months has been sent back to her country but i dearly want her back. She has been allowed to stay, live and work here for 11 years but now the home office have decided that she has overstayed and have removed her

Sorry to hear that. I think you probably should talk to an immigration lawyer. You also can get advice from citizen advice bureau.
It might be helpful if you post this question in the law category with more details about her case.
Good luck

ugh..it has been six months since he broke up with me, but i am still always thinking about him!! He is such a jerk to me, i dont even know why i like him. Is he the one for me? how can i get over this??

No he is not if he let you go. You need to move on. It will take time. Why are you even thinking about a jerk like that? You deserve better. Every girl deserves better.
