wildflowerchild, sending you big hugs I'm not sure I can add much more beyond all of the important things others here have already written in support of you.

Parents can't be perfect. Children are not perfect. The whole fact you absolutely do love your son, and do show it far more than some mothers, is significant. Being a single mother is a major challenge, I'm sure. I hope he recognizes that. He sure should. I hope that soon you and he can talk about what happened and come to a peace. We all are responsible in fights to some degree. A true apology and letting bygones be bygones is crucial.
