... but i'm devastated , he was never interested in other women when he's left before , only in the beer .
He is STILL only interested in the beer. Women, men, whatever, we are ALL just a means to an end for the alcoholic. It has NOTHING to do with you. People who are alcoholics and addicts are not looking for normal, healthy relationships. They are looking for sick relationships with other sick people who enable their alcoholism and allow them to continue to behave badly. Period. They speak in terms of romance, relationships, and love in order to manipulate you.
The fastest, easiest way out of these feelings is to bite the bullet and stop communicating with him. Stop listening to the poison of his words.
Go No Contact.
The reason he is TELLING you these things, such as this nonsense:
sorry but I had my chance !!
Is intended to manipulate you and your emotions. If you no longer listen to his words, you cannot be manipulated. The longer you go without listening, the healthier you get.
