Ok, now it sounds like you are saying that you didn’t like him but since it might have been because of the beard that you didn’t like him, you gave him a chance to come without a beard, and you still didn’t like him. Had he shaved to begin with you would not have dated him again because you didn’t like him even clean shaven. So it had nothing to do with halacha. (Minor point: In your first post you wrote “I decided to give it another shot knowing that the next time we would meet would be after tisha b’av and he would be clean shaven” and in your second post you wrote “we went out a few times over the three weeks”.)
As an aside, I realized that my first response to you wasn’t really applicable since you were discussing the three weeks as opposed to chol hamoed. But it happens to be that there are halachic justifications there as well.
