My S/O is brutally honest when I ask if he likes something or not...

Aria
Hey ladies... I'm writing because I need some relationship advice. If I ask my boyfriend if the back of my hair looks good when I'm about to run out the door he doesn't hesitate to say something along the lines of "well what is it supposed to look like" to which I answer "I mean it's not supposed to look like anything in particular I guess, just nice y'know?" and then he'll immediately say "oh, then no".... I like that he's honest, but at the same time when I spend maybe an hour on a hairstyle and he simply says no with no real input like "it's too frizzy or I think it looks a bit messy or it looks good I just don't like that style" ... If he said those things I would be fine. He does this with many other things, cooking as well.. It really hurts my feelings. Am I being too sensitive?? I brought it up to him before and he basically said "there's no such thing as constructive criticism.. Any criticism can be taken as constructive or not"... I disagree highly.. I am the kind of person to make sure I say phrases like "it's really good but maybe a little less salt and it would've been amazing!" Etc... This is the way I would like to be talked to on manners like this... I've never taken criticism very well so at least a large part of it is just me being too sensitive I think.. But it still really hurts and upsets me when he says things so bluntly with no positive outlook at all. What can I do here? I've basically stopped asking how things are but I want to know what he thinks about things.. At the same time I also don't want to feel terrible after the fact... 😞
