No here is going to make you feel any better, because most (Myself included) will see what he did as justifiable based ion the circumstances. However, you were not exactly naked, just your top half was and I doubt that he was exactly taking the timeout to stare at your boobs as he just wanted to possibly make you more comfortable while you slept. You for some strange reason have cast a doubt on his intentions so, must have had something similar happen in the past, yet you were right back then and it's reawakened a deep emotional incident that at the time you made the right decision. I know that many girls/women see boys/men as being sort of repeat offenders of many emotional and psychological drama's that many girls/women have had to endure at some time or another during a relationship, but we are not all the same so, don't tar us all with the same brush please! That said, I don't want to take away any of the hurt you feel by this incident, yet despite you also feeling a tad guilty for feeling the way you do, it's not going to still make whatever decision you do easy. I wish you the very best whatever you decide for you and you alone.
