Have the people who are ragging on Howard seen his character develop since he met Bernadette?

Genuinely curious, I'm a verry casual bbt fan (i've seen maybe 20 eps in total, scattered about the seasons) and whilst I couldnt stand him to begin with, I've found him very sweet since they got together. Pretty sure there was one episode where he basically said he's become a changed person for her? Although I hold my hands up and admit I haven't seen enough of the show to know for sure if this development stuck or if he remained creepy and misogynistic.
