Hello. Haha, yes, the heart seems to go off on it's own tangents half the time. Been there done that myself, it's nuts. I don't have any real solid advice but can you keep on reminding yourself, everytime you see him, or whenever you're at work, keep reminding yourself that he's married, that his relationship to his wife is of the utmost importance and that you don't want to jeopardize that - I'm not saying you are jeopardizing that, but it might be a good way to begin putting up a mental boundary between the two of you. Give it a try and see how you go.
