My parents bought DP and me a house many moons ago. We decided at the beginning of this year to sell up and look for a new house. We found a buyer they were a respectable couple in their late 20's and we found a new build. The couple wanted to move in when their tenancy ended so DP and me packed up and moved home to my parents as new build won't be ready yet.
I was very friendly with my neighbours have got their numbers and have been out for dinner with them countless times.
So since we have moved out I've been getting daily messages about the new couple. Apparently lots of loud parties drinking in the street, drugs etc. I've told her she needs to call the police and she's saying no I need to sort it. I have countless times said no it wasn't even my house technically and once we completed legally I/my parents have nothing to do with it. She's now threatening legal action against me (have told her to get on with it) but is there/would there be any reason for me to have anything to do with this? I don't think she fully understands the buying process on a house and is asking why I didn't get references.
I suspect she's using me as a scapegoat for other things /stresses in her life that are going on.
Not really sure how to save this friendship and don't think I can
