Speaking of pics, there is one particular photo that annoys me, and my stbxah uses it, as his desktop background and also as his facebook profile pic. Nothing special, just two of us sitting, but him kinda looking hunky and me leaning toward him (however, he is not leaning toward me to hug or anything). And last night, I was wondering why he liked that pic so much. It is at least 7 years old, and we do not have many recent pics (if any) together at all.
So my theory is that he is "remembering the old times," "loving and celebrating" the codependent me(you). Living in denial.
