What can i do to make things better between my bfs childs mother and i?

Back in january i had sent some txts to her telling her what i thought about her negatively and bad of a person she is for being a homewrecker. She didnt deserve to be called the ugly names i told her but i do believe the things that i told her was true. Since then it has weigher heavily on my shoulders and i wish i could go back in time to stop myself from hurting her an to save the friendship we had. I do respect her for being my bfs childs mother but part of me doesnt cause of her low morals. Now she doesnt want anything of me and wants me gone for good. She doesnt want me to talk to her or at her house( that is owned by the wife of her bfs) I can understand why she doesnt like me but her forgiveness would mean alot to me. I have tried texting her meany a time to ask if i can talk to her to give her my apology even tho she doesnt want me to text her. I try not to be to overbearing in fear she could get me on harassment charges even tho since jan. I havent sent anything mean or offensive to her. When i take pics of the child i send them to her cause i figured she would want them.

So does anyone have any suggestions on what i can do to mend our friendship? I know i am just a gf but my bf and i have big plans for the future and i dont want the mothers hatred for me to come in the way.

Thanks!

I am not the homewrecker because while my bf and baby momma were married she was sleeping with another married man. I had come months after they had split up. The man she was sleeping with had a wife and children of his own.
