I would also have major red flags going up as to all the nights spent in hotel rooms--are you certain that is where he is going and if he is alone? I say this from experience, my STBXAH started a pattern of leaving to "get away" from the stress & I never thought about him being with anyone else (who would have him in that state?) Boy, was I wrong. I'm only saying this for your protection--you don't need to add an STD to the chaos and heartache. Praying for you!
