His baby mother trying to contact me ?

I have full custody on my son and don’t receive child support of course.

My baby father has taken my son and put him in dangerous situations as walking on a busy street with him as a newborn with cars zooming by because he didn’t want to give him back to me to go home.

I had to call the police and after he kept taunting to me and laughing about everything he hands me my son back and walks away and police of course came late and couldn’t find him.

I had to get a restraining order against him due to him threatening to shoot me on Facebook and follow me to work all because i wouldn’t give money or not let him see our son.

My baby father doesn’t trust anyone in his family to be around Preston and his mom is a drug addict so i officially don’t contact them or try to.

He sent me $100 for Preston one day unexpectedly and i thought wow that’s shocking and after a couple days or so he requested all that money back for food, living expenses and weed..

i just officially blocked him.

His baby mother is now trying to contact me because she’s having a baby by him and she wants my son to come over to be with his “sister”.

I told them no thank you and please stop contacting me.

I’m currently pregnant myself and taking care of my son full time and to this day he’s still requesting me for money on cash app or sending me messages asking me can i give him money or sending sexual messages...

He’s saying I’m wrong for doing this and so is she but i don’t know her and i don’t want to get my son involved because she’s known for just kicking my baby father out and he’s depending on her for shelter so if anything happens i don’t want my son to be around that.

I honestly don’t feel like I’m wrong... he’s not fit to me a father and honestly I don’t know her or care to know.

I feel like I’m in the right and i told her to please stop contacting me.

When my son is old enough i will sit down and talk to him and he will have that option to visit them or not but until then I’m the parent who has full custody and to leave me alone.

Update:

I read the comments and listened to one of the comments and told the baby mother that if she cares about Preston meeting with his half sister then we can set up time in the future and meet up with the 2 kids WITHOUT my baby father and of course she said no so as of now I guess he won’t be meeting with her.
