Welcome to the board. You are having a lot on your plate.
A few corrections here. IF you guys had relations, that doesn't mean that he is scripturally free. She is the one that decides if she wants to take him back, by forgiving him, or reject him. IF she rejects him, he is free. I have known of cases where there was adultry involved, and the innocent mate did forgive, but the guilty didn't want to get back together. According to the WT standards, that made the guilty one, having an unscriptural relationship. Bear in mind, this is THEIR thinking.
But this man is haunted by the WT's thinking and will be guilt ridden for the rest of his life. RUN as fast as you can, if he cannot decide he wants you. It's going to be hard, but the longer you are in the relationship, the harder it will be. You don't deserve that, and you are making it harder on yourself.
If he's really interested in you, than he will do WHATEVER it takes to be with you. His actions will speak louder than words !
