If he's still using the account and lying to you about it then it sounds like the only way you could fuck up is to waste anymore of your time on him.
If you want a friend with benefits that's one thing, but it sounds like you're looking for more and that he definitely isn't. It's not a good fit, find someone who is looking for the same thing you are.
