We have a ldr. I have questioned infidelity several times. He found a bottle of bath and body lotion in his van. He does have 2 older daughters who may have been in the van since i was here last. But we were cleaning it out and he seen it and said is this yours?, It was in here. Funny thing is its a 2021 summer scent. The van has been cleaned out several times cuz he delivers paper in it. Am i crazy to believe that he doesn't know whose it is even though he asked me if it was mine ?

If you have a history of suspicions then it's not crazy to be suspicious all the time, but certainly not healthy for this relationship or any when small innocuous events get that suspicion going again. Does he have trust issues too?

If so that's a double whammy.

I’d ask the daughters. If they are old enough to drive, have their friends been in the van? Lots of possibilities.
