Your emotions/feelings can change on any given subject over time, but your actions are permanent. I think it'd be worth the risk. Better to be turned down than to have her sitting there stewing thinking "and he doesn't even want to come be part of our family".
I've always been very independent. I've done a lot with my kids and most without H. But looking back over the past 10 months, from a friendlier co-parenting place, I think I would have felt better about including H in some family time. There were too many raw feelings, but if he had asked to come on any of our trips it would have really changed the dynamic in our R.
Even recently my H sent me a suggestion for father's day and I got on here & wrote about how presumptuous that is blah blah!! But in the end it's my opportunity to be the best me if I feel like showing grace, and it makes me feel good about myself. And those are positive feelings!
Consider giving your W the chance to make positive choices and have positive feelings towards you. And if she chooses to say no, she'll never be able to accuse you of not caring.
It doesn't have to be all serious, you could just admire the clothes on display and mention how excited you are for them and has she thought any about you coming along? Because if you're assuming that she'll say no, isn't that mindreading or more-of-the-same behavior?
