Yes, Angel, you WILL be fine--and believing that is really the secret to life, because it means that you no longer depend on others for you happiness, but have found it in yourself.
As for doing the right thing, that's a bit of a tricky concept. I remember the first time I came on the words "Be right or be happy" on this website, and realized that's where I'd got caught up during the first few years of his MLC. As H became angrier and pulled away from his children, responsibilities and me, I knew he was doing all the wrong stuff and tried to pull him back at first, then gave up on him for a while--but it was all done with anger, hurt, righteous indignation, and the feeling that he was the "bad guy" forcing a terrible situation on our family. I may have been "right," but I was consumed with anger and felt like a victim.
Then came the day of the bomb, when I asked myself if I still loved him, and resolved to act out of a loving place--towards him and myself. Whether he chose to stay in the M or not, I would stop behaving in any ways that didn't make me feel I was acting from my best self. I went through what I felt was "right" for me in all my relationships, forgave myself for not knowing enough to do better, and envisioned how I would behave in the future. And I became that person, knowing that all my changes were right for me.
Eventually, I got to the place where I knew I could be fine without H, where I could visualize life without him without pain or distress. But it wasn't about doing the right thing--which is difficult to gauge, because everyone has a different perspective on it--it was about finding and embracing my strength.
So perhaps what you're saying is, you will do what's right for you--and that includes honouring the boundaries you have not yet explored or articulated?
