If you feel relieved for now that's good but let it sink in. It is a shock and even though you have been contemplating this it still very shocking when you say it for real and you believe it.
Now I wish I could give you the big hug you wanted to give me yesterday (or was it this a.m.?)
I think you have done an amazing effort here and you will be able to carry this into a new R. This will take some time though to work through and I would recommend IC.
The one mistake I made in my first M (wish I had this place then) was I ran away from the heartache and didn't deal with it for many years. But it catches up to you in the end so don't run away. Deal with it head on with all your courage you have shown us here.
I am very sad for you both I must say because I feel you really gave your all to this and I know that this man will regret what he is doing.
When this settles in you will know in your heart and your gut I think (if you don't already)if this is right for you.
My goal is to some day be the person my dog thinks I am
