Like I said .. do not go there ... heck .. I am not so sure about the MothersDay stuff either ... that is all from you and not the kids ... in line with the Birthday gift stuff that people (myself included) always struggle with.
Here is the deal ... the FB, not your circus not your monkeys ... let that go, seriously ... you can not do anything about it ... consider that a small campfire, you are walking around with a bucket of gasoline and trust me, this will burn off your eyebrows vs putting out the fire... no good can come of this. You are in NO POSITION at the moment to demand/question such things ... there is a time and place for that ... here and now is not that time and place, please trust we are trying to help you here ... think hard about it.
Also ... if it were me, I would not do all that for Mothers Day ... Last year my W was further out than yours was, I helped S get her a small gift and that was that. I was a chronic pursuer, would buy a $500 gift for her and in exchange get a bag of socks .. this was Pre BD.
At what point has your W had to face life without you?
Think about ^^^ ... you can not spoon feed or nice her back on one front and then go Alpha Male on the FB on another front ... you need to become detached and consistent ... get where I am going here?
