Can my child's father get full custody of my daughter?HELP PLEASE?

[IllestGirl]

So my daughters dad said he wants to take me to court to fight for custody. Is this possible? I have no job(yet, searching very very hard) but will be attending college this fall. Also he sells drugs but just got a legit job somewhere, all he does is party , hang with his friends and do drugs.he has put his hands on me before, the last time he did i called the police but he left before they could get there so they wrote a case nimber on him. That same night he sent his sisters and cousin to my house to fight me. He always wants to argue via texts and has his girlfriend harrass me on twitter. Can i use this against him in court? I am 18 and he will be 20 this october. Please help I really dont want to loose my daughter so please only serious answers, no smart asses
We live in Pa

It is possible that he could get joint custody. Most courts will not take a child away from the parent who has the child living with them and give full custody to the other parent unless the parent the child lives with is proven unfit.
You need to start keeping a record of his abusive actions toward you. Let him text you, but do not respond back in a negative fashion. Keep the texts so you can show them to the court if he tries to take you to court. Also, call the police anytime he harasses you, or any time he sends anyone to the house to harass you. Also, when someone harasses you on twitter or facebook, resist the urge to respond to them. That way you can provide proof in court that he had people harassing you, but that you did not respond.
He probably won't actually take you to court, but if he does, you will have proof that he won't leave you alone.
