Regardless of whether it is fear or annoyance, he still has not right to be snooping. Remember, he made the choice to leave and go to the OW, not you. I think part of this whole process is taking a little of ourselves back. You have a right to feel comfortable and safe in your own home, and he gave up the right to come and go as he pleases when he left.
It is about setting boundaries. It doesn't mean we love them less, but love ourselves a little bit more.
Im still standin better than I ever did looking like a true survivor feeling like a little kid Im still standin after all this time and Im picking up the pieces of my life without you on my mind..
