How's the vacation going? I'm sure you didn't spend much time at the beach w/the weather the way it was.

My weekend was great. Got a lot done, went to an Artfest and met up w/some old classmates for dinner. I've been enjoying the rain because we've not had a good rain since June.

I would definitely tell your ex-SIL about the comments. I don't trust RT one bit and your xh is just blinded enough by "love/oatmeal" that he would go along w/anything she said.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
