You need to GAL. I lived through this for the last year. the first 3-4 months were killer. All the vets around here kept telling me to GAL. You need to move on and start doing activities not sure if you said you had kids but if you do start doing things with them. Join a bookclub and give H the responsibility of taking care of them. Pick up a yoga class, join a gym.
Fake it until you make it. Let him know you are moving on with your life while he tries to figure his out. yes this is very hard trust me it took me until now to figure it out. We are in the process of a D unfortunately we aren't able to divorce bust but being here I learned to GAL and it is the best thing I ever did. I had to try hard. I started hanging out with my family members and making myself go to food fairs and vintage fairs etc with friends. I joined Facebook and reconnected with some old friends to keep my mind busy at night so I didn't sit and spin.
Get yourself back the one he fell he love with. It sounds like maybe you were independent but fell into the parent/marriage trap and lost yourself. I did the same thing but guess what the old me was there and now I am not a doormat waiting on him.
