Can you be friends with your ex? Like honestly I still love him and care for him I always will but he has a girlfriend and with that he still always comes back into my life. Whenever I think we're done for good he always  comes back. But this time he wants to be friends. Why? Like why does he want to keep me in his life? Why doesn't he just leave me alone ? Do you think it will be hard to be just friends ?
