I want to get a young family evicted from my apartment complex
Why do you want to get them evicted?
I got the mom pregnant and she is insisting I pay for all the expenses while she sits at home blasting loud music all day.
You shouldn't try to get people kicked out of their homes. If they are causing a disturbance, you should report them to your landlord and let them deal with it.
If that spoiled bitch wants to have my baby she should get off her ass and earn money.
Well it sounds like you need to support your child if this is true. I would request a paternity test when the child is born. I can't believe you would cheat with her and try to ruin their family.
