Neighbors..

It's 11pm right now I'm in bed we live in a townhouse and own ours.. She just bought hers and has been moved next to us for like two weeks and we've had to call police once due to loud music yesterday it was loud we let it go it was a Sunday night!
It's Monday in home alone husband is at work I am third trimester bed rest with complications..
And allllll I freaking hear is music!! I wanna rest!
I won't go over there and here's why Saturday my husband and I were outside on our porch there back door was open its a slider he hit her!
She screamed then he closed the door..
I refuse to deal with that man!
He hits me or yells at me id knock him a new one!
Husband says call cops but I don't need drama between us we just moved in here in October Ughhh I will never buy another townhouse!! Next one will be a normal house away from others lol..
Question is what the hell do I do? I refuse to knock on there door due to that man and me needing to rest..
And I don't need issues.. Like seriously!
:( lesson learned..
