You seem to think that if you don't kiss him, nothing is happening. That isn't true. If there was nothing, why would you have even discussed boundaries with a MARRIED MAN? It isn't fair on his wife, who, if she has eyes in her head, can see that at least you have feelings, and possibly her husband too. This man is prepared to hug you and include you in social events, and be a confidant to you, knowing what inferences his wife will draw from this, no matter what he, or you, may say. He doesn't sound like a very nice person, because, make no mistake, he is hurting his wife by his closeness to you, even if she knows he will always come home to her. And frankly, if i was his wife, you would have been very firmly been set at the correct distance, with a very clear and plainly-phrased warning to step over my boundary at your own peril. No one can tell you not to feel something for him, nor should we, but have some self-respect, and some respect for another woman, and keep yourself at enough of a distance not to risk hurting people, yourself included.
