Oh, and change the Wifi password. Lets see if that is why he is coming round. if you need instructions on how, just ask.
Yes please! I have no idea how to do that!
I have been thinking about this, and I'm not sure it is the right thing to do. Is there no cafe's or place he can get wifi? There probably is, right? I don't think he is there for the wifi. I just see doing this as a an unnecessary point of conflict. Maybe try asking him to not be on his phone so much and if he wants to be in your house with the family, be there. If not, be else where. I'M NOT A VET. I think just let it go.
I think this is just something that my prior to BD passive aggressive self would do. I'm working on that.
