sisabel, you carry guilt for whatever you did not do when it came to raising her. Well, you can't really change that and no one is THE perfect parent. It's ok to have boundaries, even when our children are grown they still test boundaries and actually learn from us about boundaries. You are continuing to grow and learn as a person too, you realize you need to work on your boundaries and that's something we all work on in our lives. You are there for her, yet you also need to have boundaries. You never know in that at some point she may see the dysfunction in her husband and either put her foot down OR may have to make the choice of walking away, yet, that may not happen for a while, may never happen. Meanwhile, you have to show her by example by practicing what it means to set healthy boundaries, even when it can be a challenge for you.
