I do not think that is a good choice for you to make avermont. I think if you do this it will take you back to August. I think you should take this time to work on your grief. You are cycling at Bargaining right now. This is OK. This is normal what is happening to you. If I was you I would take this time to work on intimacy with yourself. Open up to yourself on why you are in this stage of grief right now. Try to figure out what triggered this. And work through it. I have felt this as well. I worked with myself on it and journalled.
I truly thing that it would be a mistake to give up all your hard earned work from the last 4 months. Continue to grive the loss of the relationship. Talk to us and a good close friend on this. Stay strong.
