I can offer for wh to eat with us on the Sunday, but would that be classed as pursuit?? I know how I felt on mothers day and got to spend it with my kids which I appreciated. Gifts are made and are from the kids, not me.
No that all sounds fine since the kids will be there and it's really centered around the kids spending time with H. Just don't have any expectations that it is changing anything and you'll be fine. No R talks either. Just focus on it being a nice, relaxing time with the kids.
