Hello M.
The feelings of loss over what you thought was a forever relationship in normal. Grieving is done at different times and in different ways. I am sure that this feeling is normal and just a part of the process of tieing up loose ends.
Talking about this is like you said very therapeutic and can help you see what it is you want in your life. Maybe there were some aspects of your past life that you miss very much. You must of had some good times since you said you were married for 18 years. Check that out. See if you can recreate with your new partner some of the things that you are missing.
Also, having children with your ex-partner will make you remember some of the good times you had. Don't push that out the door. They are real and valuable feelings and memories. Denying those memories would also deny your children's expereinces as they grew up.
Starting over after a divorce id never easy and does that time. I've been divorced from my first spouse for 21 years and there are times that I feel sad, not because I would like to go backwith him, but sad because I see him alone still today. I once cared enough about him to be with him and have a child. I think it's only normal to still have some feeling towards this person.
I hope this was helpful and useful to you M.. If you would like to talk some more about this, you can email me. I work with stepfamilies and help them work through the transitions in creating a new family. Good Luck
