Sorry you are going through that. I just went through that and the marriage completely crumbled.
After having been through it for 7 or 8 years, trying everything to make things right, it's a huge relief to move on. In fact, it's exciting.
For the first time, my whole world has opened up.
I do hope that you can figure out a way to make it work. However; please know that there is life on the other side. You will get through this and you can be very, very happy.
