Not sure if I should say something
My neighbor and I are really good friends. Our kids are close in ages and we share the same babysitter for weekday afternoons. She and her kids were in Florida visiting her parents for the first half of last week, her husband stayed behind for work.
I was in the kitchen preparing dinner on New Year's Eve when I saw the babysitter pull into their driveway around 6; I didn't really think anything of it at first and didn't look again the rest of the night. I'm generally an early riser and I saw her car was still in their driveway the next morning around 7, this is when I started to get suspicious. I went about my errands, when I looked again around 8...her car was gone.
I told my husband what I saw and he also thinks something might be going on. He said the next time he has a chance to chat with the neighbor, he would try to bring it up; they're decent enough friends. I just don't know if I should say something to my neighbor or wait until my husband gets proof. I certainly don't want this woman as a babysitter if she is sleeping with the neighbor's husband.
