or were your intentions for him not to see you..i.e. parking where you knew he wouldnt see you, or expect you to be. from what i can tell by your story that part is not clear. in my job we help clean each others cars off. especially if one of us forgets their snow stuff and it snowed while at work...we work shifts and we get off at the same time...so its not uncommon to see a guy help a woman, or vice versa. what you dont know is that maybe he was being nice and that you really didnt give him the chance to do it in front of you because he didnt know you were there. its very possible that he would have done it with you there. its just that you were not seen, so therefore you thought he was being sneaky, when in reality, you might be seen as the one being sneaky because you didnt make your presence known...maybe you could have approached as soon as you saw him start to clean her car off....too many variables here to define that situation...i am not taking his side, and i dont cheat (i think my woman does and thats why i am here)but i just was posing an alternate idea to you...good luck though...and i hope he means what he says to you
