I'm not sure I understand what the problem is here.
Your wife quit a gambit match to care for your baby and got a mean message at some point afterwards and now you need to come to the forums to be mad at everyone because somehow its our fault?
I would think an adult would be able to ignore something like a (I assume) pm in a video game and not be so upset that strangers were mad at them when they had no idea your wife had a good reason to leave the match.
If your wife, or you, is so emotionally fragile that you can't handle people being upset with you in a online game after you left a group with no warning you probably should not be playing online games with people who you don't know or haven't been told that you might need to bail for your kid at any moment.
