Well, this may seem a superficially simple answer, try the book The Care and Feeding of Husbands by Dr. Laura. Basically, along the line of strategy of REL-give more positive attention to him, about him, for him. It doesn't have to be about sex; a foot rub, a gesture or statement of gratitude for what he does (at work) without qualifying statements of compairson to what you do/have to put up with. More positive attention, guys like attention.
This should make some progress if he respects you.
However, your examples in OP begin to suggest to me, imho, that his respect for you might be slipping. The comment on the bus was blantantly degrading you and publicly at that.
The making up things in his own head is - well, here we go- called 'gaslighting'. It is a technique controllers use to make the subordinate one doubt their own mind. The controlling modis operandi is based on a foundation of disrespect. (He used his sister to degrade you through diminishing her opinion of you.)
If this is the first time that he has done it, you probably don't believe it. It is a slow drip kind of damage, but very serious damage and difficult to recover from.
Or perhaps he is making these comments publicly if he knows you will not protest in the moment. What was your response? Nothing? (Even if it was a shocked nothing...) Then, in his mind anyway, he is correct and he won that one.
It is late here, but I need to ask: are you moving away from your family and friends? If yes, then this is a great big red flag and your dp has tipped his hand.
Regardless of what you think of my post, please read "Why Does He Do That?" by Lundy Bancroft.
Sorry to turn a doomsday perspective loose on you, but please don't marry him or have dc (if you haven't already) until you get this figured out. If something I've written rings any bells, consider 'postponing' the move. No you do not have to go (and I know I don't know your circumstances, sorry). Emotional Abuse is never something to 'settle' for; you are better off without men(or women) like this in your life.
