Feeling alone

Greetings all

I'm really in a tough place at the moment and am seeking some wisdom and support . Feeling really low .

My wife and I have been married for over 28 years. We had our ups and downs over the years, had a close call with a near divorce years ago mostly due to my issues and partially due to hers . We both got individual therapy reconciled/relocated and restarted our lives and today she suggested that it might be better for both of us if we divorced as she was not sure we could any longer provide each other what we needed emotionally . She explained she wants to work something out amicably without any lawyers in a way that minimally hurts either or us financially .

She says she is a wounded soul and I shouldn't have to be with someone with her struggles . I love her so very much and am happy to face those challenges. I suggested marriage counseling but she says she's not sure if she can do that and will have to give it some thought. I am far from perfect and fail at times to show the right emotional support but neither does she (which she readily admits)

I am hopeful that things can be figured out and we can save this but I am devastated and to be honest terrified about the concept of loosing who I thought was my soulmate and best friend . I am also terrified of living alone after having a partner by my side for almost 3 decades to face life's challenges with.

I don't know how I will deal with the loss of such a big part of my life or starting over both financially and emotionally if this happens. How do you get over almost 3 decades ? How do you start your life again in your mid 50s ?

Feeling lost and hopeless at the moment.
