You just dropped some serious pearls on this thread! I needed to "hear" what you just said too, so THANKS!
Sydney,
I was about to say,"Yeah, what 25 said!" lol ! There is not much to add but I will say that your daughter is watching no doubt. She may not tell you how she feels for years to come. Show her what a healthy relationship looks like so that she will be able to discern it for herself when she goes out into the world.
Help her through example to end a cycle of codependence and putting other's needs before her own, as you mentioned. I was raised very religious and codependent as well. My Mom and her Mom were both this way. I am trying to break the cycle so that my daughters pick better mates and are more self aware than I ever was.
I applaud the work that you have done to this point ! Keep moving forward and doing the things that make you happy and fulfilled. You are doing well.
