I believe it exists. I know two couples who have been married 23 years. They seem happy, I'm sure they have issues but they choose to hang in there and solve them. Love is not based on looks alone or sexual attraction. There has to be other factors to keep a couple together like communication, common interests, commitment. I've had good relationships and I'm presently single. I've learned it is better to be by yourself than be involved with the wrong person. So you have to be patient, keep trying and love will find you. I'm not giving up.
