How to Prevent the Father from Having Visitation

My question involves a child custody case from the State of: Pennsylvania.
My child is 14 months old. I have never been married. The biological father is not on the birth certificate, does not support the child, and has very little contact/visitation that did not begin until my child was 4 months old. He also has a 4 month old and is engaged to another woman. He has a rough past and family members. I am worried when my child is with him. I am willing to do anything legal so I do not have to let him see her anymore. My boyfriend and I have lived together for a year now. We are both doing well financially and want to move on without this cloud of instability above my child's head. We have talked about engagement and he would like to adopt/support my child.

Is there a court order for visitation?

If not you don't have to allow it. But if you suddenly stop, expect Dad to file in court for an enforceable visitation order.

That is what I expect, I am posting to see if how I might legally be sure he can not see her again. For example how long does he have to apply to be on the birth certificate? Is this a case of abandonment? And in the best case scenario how does my boyfriend adopt?

we have not been to court about any of this

Your boyfriend cannot adopt.

You will have to be married, and remain married to show the court stability, in order for a stepparent adoption to take place.

There is no abandonment here.

Thank you for your time first of all. To be clear, I do not have any options.. If she turns 2 and he still does not support her or attempt to get his name on the birth certificate does he still have any rights? And am I able to move to a different state to attend college now? If I left could he force me to bring her back to see him?

He has right up until she turns 18 to establish paternity.

Yes, if you leave the state he can file to have the child returned.

Whether or not he'll be successful, anyone can guess.

Quick question though - how often has he seen her?

Maybe 15 times, ranging from 1 hour to 10 hours.

What cause do you have to demand he not see her? Take responsibility for the fact that both of you engaged in making this child, and this child is both of yours. The fact that you want your boyfriend to adopt sounds pretty impulsive and manipulative to me. If you cared so much for your daughter why would you take her father away like that?

I am the one who contacts this man every week to see if he will be coming and make the plans on going about it. I realize I did not post very much personal information but there are many things that worry me in this situation. I have tried since the day I found out I was pregnant to be civil with him. Most of the time I do not hear from them at all and he has made the comment many times that when she is not around him he forgets about her.

by "her" i mean my daughter

That's really a considerable amount when you factor in that there's no order, at least when it comes to comparing to abandonment. Which really doesn't apply her at all anway.

Why in the world would you want your boyfriend, whom you've known all of a whole year, and whom you are not married to, to adopt your child? Please tell me you are not teaching your child that he is daddy?! Either way, thinking your boyfriend has a possibility of adopting does not show a lot of stability and long-term thinking on your part.

No one is going to hold it against him if he doesn't pay any support if their isn't an order for him to do so.

The only real way to prevent dad from getting time with your child is to not create a child with him in the first place. You can't change the choices you've already made.
