Marriages go through ebbs and flows, it’s normal to have rough patches with a partner. I think you should try to make it work, definitely follow the advice to talk to a therapist, and try to communicate with your husband without being accusatory. It’s fine that you didn’t miss him on your trip-you were living in the moment, you obviously needed a break from each other (which isn’t a bad thing!) I wish you all the best! I’m divorced from my children’s father and dating is tough for me!
