^ I was just thinking about this. People change and so do relationships. I know that at one time I considered my wife to be my "soul mate" and I couldn't have imagined being happy with anyone else. However not only has our relationship changed in the last few years, but both of us have changed in terms of personality and interests. I no longer feel as close to her as I once did.
I have no idea how things will work out in the future, but I am sure I would never regret being with her or have ill feelings.
