It hurts and I can't stop crying!

I love my boyfriend more than anything in this world! I'm leaving everything I've known for over 23 years to move out of this country so I can be with him and his beautiful daughter! I know a lot of people would tell me I'm insane for doing this! But this is truly what I want and need for life. He may be only 19 but i have never seen a 19 year old love their child of care as much for their child as much as he does! His little daughter means the world to me I love her just as much as I love him. I love talking to her every weekend and hearing her say she loves me and she missed me and she can't wait for me to get there! Her mother in my eyes and in the eyes of others isn't the best. She parties a lot, she lies, shes always in unstable relationships and moving around a lot. She drives with out a license and that's really dangerous! I want to protect her so much and give her whats best and I want Her and him and myself to be a happy family! But I came to the realization today that, that won't happen! I know her mother would never ever be willing to give up custody of her, even though my boyfriends mother and family and him and myself knows it's better for her! And as much as i would kill for that little girl and how much I love her I had to make the adult decision to realize that I can't always have what I want! My heart is sad and hurts and is scared for her and i can't stop crying right now! I love my boyfriend and her so much!
