Opinions please. Sorry for the length.

My SO has a one year old son, he is my everything, I treat him as my own, I love him dearly.

His sons biological mother is not around. She had him till right before he turned one, until my SO got full custody.

She has two days a week, supervised visitation, for an hour, by my SO.

SHE ASKED FOR SUPERVISION. She also did not put up a fight.

She hasnt shown up for over a month to see her son because the place the visits where held, she did not feel comfortable at.

Thing is, she has never asked to meet anywhere else, and she never told my SO she didnt feel comfortable until he FINALLY got in contact with her after not showing nor contacting him for over a month.

We have offered to meet somewhere else, still a no show or no contact.

Mind you, I get along fine with his biological mother.

My SO son calls me mom, because I am there when he is hurt, I teach him, I take care of him, I put him to bed and feed and bathe him 24/7.

When he does see her, he acts as if she doesnt exist because she has nothing to do with him, even at her visits.

I am not the type to call myself his mother because I simply am not. She is. I dont want to be the selfish person to do that. But, I do look at him as my son.

Im just not sure how to respond and act with all of this.
