    I would love to be able to redo how I felt about marriage. I had low self esteem, and said yes to the first guy that asked me. I was afraid that no one else would want me. I ended up divorced. You should never settle for less than you want in life or love. I am remarried now and can tell you the most important thing in any relationship is communication. If something upsets you - don't ignore it. Too many of those harsh feelings erupt into a huge fight that may have been avoided. A lot of times people can be offended in a way that was unintentional. Communication is the key to a healthy relationship.
