UPDATE: DH got ahold of FIL and took my side. He confirmed that FIL did infact leave the items in plain view. He booked FIL a hotel for a few nights until he goes home and agreed that this was the last straw.
Edit: for the last time, my boys didn't go through his stuff. He left it on the bathroom counter in plain view.
So my FIL is visiting for a couple of weeks. We have given him the guest room and he is sharing our second bathroom with my 6 year old twin boys.
I clean the bathrooms daily because little boys are gross lol. Well yesterday I cleaned it and put thing away, everything was nice and tidy nothing unusual.
This morning FIL slept in and I heard my boys getting breakfast. I slept in a bit longer until it got really quite. I got up to investigate and found my twins in the bathroom playing with condoms, lube and a fleshlight.
WTF! I am livid! I barged in on sleeping FIL threw the crap at him and told him to pack his shit.
DH is on his way home from work.
I'm just pissed. He is a grown ass man and had no common sense!
What would you have done? I hope I not overreacting, I'm very hormonal. I just feel like he violated my home.
