ZHi all. So step mother in law and bils and sils ( there’s a lot) are pretty close to us here. And we want to be around them and hang out, invite them over. Usually they are tight knit with each other, but their behavior has affected our closeness with them. SMIL was given bedbugs while living in same house with landlord. She proceeded to pass them on to us in our new apartment the first time she was over. I ended up discovering them when my first DD was born, and having to work on ridding our house with DH  while I was home recovering and for 7-9 months after.
