At some point, I'm going to have to come out to my son's other dad. He's going to notice. He is ok with lgb people at least (I don't know what he thinks of trans people) and he's fine with gender bending, but we didn't end on good terms. I am going to wait until custody is sorted, but the fact of the matter is, he could restart it if he wants.
How do I go about doing this?
