Boundaries in Marriage is one of my top 3 favorite books of all time. Meaning it was totally life changing for me in terms of how I viewed my marriage. I never really set nor enforced any boundaries with my H and thus was always in 'victim' or 'reaction' mode. I thought I could "love him back in the right direction" and that just didn't happen.
I think it is an amazing book and I do hope you enjoy it when you read it. Lots of valuable insight there.
