If memory serves, you told H when he moved out, that you were not interested in "dating" him if he was "dating" other women. Now it seems that he has dated other women. The only question is, has he stopped dating other women?
His comment about only wanting to "date" you and have "platonic friendships" with others is too vague--he could mean anything by it. Before you agree to go out with him, it is necessary for you to get a concrete definition of what things he will and will not do. Not you telling him what is acceptable, but him telling you what he intends to do with his "freedom." And then you can decide whether you want to be part of that or not.
