Hi Combakkid,
I totally get where you are coming from. I've been married 18 years and just come to realize in these past 6 months what is really going on in my marriage. I always thought everything was my fault. And even though I know I bring my stuff to our dysfunctional relationship, the excessive use of alcohol, has truly changed my H (along with a lot of family stuff). I have read Co-Dependant No More, along with many other of her books....and so many others. I too, feel as though I have no support or friends and it gets really lonely. I reach out here on occasion.....and it's been helpful.
Keep reading and learning. Take time to really care for yourself. It gets hard when you change and your qualifying spouse isn't. That's where I'm at. I take each day as it comes and I try not to think too much about the future.
Peace ..... Mauihope
