My 17 year old son doesn't want to talk to me. He lives with my STBX and doesn't want to contact me after we filed for divorce https://onlinedivorcer.com/online-divorce-massachusetts. He recently bought a tattoo gun. My STBX didn't tell me this. I think this is a bad idea for him. I discussed this with my STBX.

he is OK. I feel like I have no say in this or anything else in my son's life. This is the last incident.

I worry that he encourages him to take risks. he at least justifies it. he says he talked to him about the risks and asked him to be careful. My son has a very good head on his shoulders. He is also a teenager and is going through hard times due to our separation.

Am I wrong about this?
