Of course you miss her! And if you want to know if she's missing you, then you have to give her a chance to miss you. The moment she reaches out will be a million times better (and worth it) than if you'd make the contact.
It is hard and it can feel a bit like game playing as if you're playing hard to get. But your W was hurting a lot when you were emotionally unavailable, depressed, and in your own words belittling. So give her that space to heal from that and let her see you as a safe place to be herself again. right now she doesn't see it that way but she could again if you keep the road home paved smooth.
Being out of town will probably be good for you. Have some fun while your gone since you won't have the responsibility of the kids. Whether that means a round of golf, a few drinks, whatever. Just make sure to enjoy yourself a bit.
