This is not JUST stress, stress can affect the body symptomatically as well as mentally and obviously lack of sleep contributes to these feelings.
I had to go no contact with my ex, he is a narcissist and although it was inconvenient to change phone numbers and update important people about those changes it was the only way I finally got rid of him, that and physical distance were what saved me.
he was sober and lovely for the first year of our relationship, things started to change and I didn't notice and after 3 years as a couple we then spent the next two years going around in circles as far as his promises and my giving into the lost little boy who had no one else, or so I thought then.
Pleas don't waste anymore of your precious life in thinking about the future even containing this man.
Destressor, sleep, look after yourself, eat well and keep doing what is good for you.
Keep on keeping on.
