It is hard to step out of the box, but empowering at the same time. I only have a handful of close friends and they are all married with young kids. I try and plan things with them far in advance and get in on the calendar because they cant do last minute things. I also found a meetup group that I really like. I don't get to go to all the meetups because I often have the kids, but I do get to some. I just signed up for golf lessons on one of the nights my H has the kids. It gives me something to do. It is a group class so I am not all alone. Before the golf lessons, I took yoga.
Enjoy getting dressed up and looking HOT!! Your H may not say anything, but I am sure he will notice.
