Maybell - this is just me - but I think reacting out of anger never helps the situation, particularly if your kids are around and, much like the decision to unfriend, you should let this sit for a day or two. If its possible - I would try to just maintain the status quo (not sure how long your exchanges last) and not let him see you are upset. I know that is very very hard to do - and lord knows I have failed at it several times recently. Worst case scenario - maybe tell him you will talk to him about it later.
