The title may be somewhat misleading. I am thinking that when you say "I continued to work with him every weekend," you were not attempting to imply that you continued a physical relationship with him. But your choice of words leaves this possibility open. If you did, it still did not excuse the fact that he took advantage of you that night, and some would call it rape. Maybe, even if it was only that one time, you just to just kind of let it pass because, as you say, it was less humiliating to be thought of as a slut than as a rape victim. If so, I am not criticizing that. But, and I realize that others will differ with me on this,if you did continue a sexual relationship with him, that kind of changes the picture, even if it doesn't excuse that first event. Or maybe this could be a kind of Stockholm syndrome.

Also, from a male standpoint, I have a question about what you said about when it became "too late" to decline. This is your statement, from your viewpoint, not his. Does this mean that you think that you led him on (further) at each of the stages you describe, and that you would have felt guilty to then say no? I would be really grateful if you would expand on this.
