"You had already invited her so there's no sense to go back on that. Since you're going out, you might as well make it the best experience you can and slowly introduce her to the new and improved you."
I say Bingo to that statement by Mr. Bond. I wouldn't back out at this point. Just have a decent holiday without ANY expectations, arguments, pressure, relationship discussions, anything like that. Keep it strictly parental. Be civil with each other and make the day about the kids.
Right now I'll bet this seems like it will be the longest week of your life waiting for Easter and waiting to see how well you cope during the holiday. But take a step back and realize, that, this time next week, Easter will be over and you will be able to continue learning how to DB without the pressure of getting through the holiday. Metaphorically, this Easter is a 5 second clip of a 3.5 hour movie. Don't put any stock into it if you have a respectable day with her, just hold your head up high because you're attempting to show your kids a nice Easter.
