Help Its very important?

I have a girlfried that I have dated for 18 monts, she has 4 kids from 4 different fathers, she was very nice at first, I'm paying all her bills including home furniture and rent, She has changed so much, she wants to do things with her "friend" without telling me anything about it she is aggressive I'm currently a victim of domestic family violence, I said that I was going to go to her house at2:00 to buy her an iphone, I got there and she already had plands, she left me at her housre but I followed her, she will stop and back up into my truck, finally she park into a gas station I parked on the from she spoke to me friom the car asking me to syop following her and she back up and step on the gas and hut my truck in the side, I don't know why she got very upset (today is mothers day) in our culture, I think she is with someone else on this day unsted of me. Please tell me what should I do… God bless you

There's a really high chance she is seeing someone else. Talk to her about it.

The fact that she has already had four children with four DIFFERENT men is a bad sign.

She is seeing someone else, that is why she is so aggressive towards you because she hopes that you'll just back off instead of finding out she's cheating on you.

Stop paying her bills. She can figure things out for herself.

What do you mean by being a victim of domestic violence? Do you mean that your girlfriend is beating you up?

Maybe you should dump her, you could do so much better
