Give me strength

The only place I have to look for strength is in Him. I have to be strong for my daughter and for myself, but I am so broken-hearted. How you do get over a love that you know will be there forever? I know this is something I have to do, not only to be a better mother but to prove to myself that I have the strength. Please Lord, I believe in you and love you and know that you are there for me. But now, I need you in my face, helping me everyday. How can a relationship that does have love in it fall apart and be so hurtful? I have tried to make it work but I feel like because I try to be the imagine that God wants, I am getting pushed around and manipulated. I thought he would be the one that I would marry and now feel like a fool?
