If I had seen what you've seen in just a month, OH how my life would be different now.
If you stay with this man, you are inviting a life of misery. You are more than welcome to read my posts if you would like to see how you will feel after 14 years of it.

RUN don't walk away. Get into AlAnon and find out why you are attracted to addicts.
