I am tired, so this may not be as coherent as I'd like it to be or perhaps that will work in my favor. I love my girlfriend deeply, I can't imagine my life without her. But I'm afraid that I'm not the man she needs. We have some fundamental differences on somethings, mostly religion. We can work them out when it is just the two of us, but she has a son and I can't just think of things as she and I. I'm worried, I'm not the best, not the best for how she wants her son raised, not the person that she wants as a father figure.
I should clarify I know she loves me and I know that she loves the man I am. I even know that she thinks I am sweet and good to her son. But I fear that is not enough, that she may always feel like she settled with me because I do not believe the way she does. Yet I don't want to let go of her, she is my world. I feel so lucky to have her, I feel lucky to have her son in my life, but I feel selfish if I don't consider that I'm not the best for them.
