We all make decisions in life where when we look back we question why we chose the path we did. But we should never regret anything as regret is a dark path that will never help you move forward. Just accept that that was the best decision you could make with the current state of your affairs and deal with the consequences the best way you can.
Many times I have looked at situations I acted in a way counter to what I would perceive as normal for me and only later understand or realize that it caused my path to move into a new area of wonderful experiences. Have a creative day.
