Just found out that my girlfriend is pregnant. I'm not the father and want to be with her to raise the child as our own. At the moment she is thinking whether to end the relationship due to guilt for sleeping with someone else or stay and try put the past behind her. The father does not want to be involved in the child's life. I love her too much to let her go and I want what's best for the child. Please give me some advice on what I should do...
