Wait did he tell you you only look "okay" without makeup or someone else?

Because if he's not the one that said it, I don't think it's fair to assign motivation to one night where you got dressed up, went out, had a good time, and he paid attention to you.

If the night out is an unusual or special thing then it's definitely very normal for there to be added attention. If you want him to be more reassuring about your normal appearance because you're nervous over things other have said, then tell him that.

But if he's the one who told you you're a bombshell with makeup and only alright without it then that's a crap partner who's making you feel bad and should be dealt with accordingly.
