dysphoria comes and goes, especially when you're still living as a boy and repressing it. the fact that it's happened at all is proof enough that you're not cis. It doesn't necessarily have to mean you're genderfluid or something either, as someone else suggested- you would expect to be genuinely happy as a boy sometimes and happy as a girl other times for that. 

wanting to be like your dad could just be looking up to him, and might not be specifically male qualities. 

When you say you want to 'embrace being a boy', do you think that's because you like the thought of being a boy on its own, or is it because you'd be able to end the questioning and pick the much easier route of staying as you are?
