Also, there's more to life than marriage. You can live a fulfilled life without getting married. I will never marry (and since the opportunity to do so doesn't exist I don't need to worry about it ever happening). That doesn't mean my life is meaningless.

You really need to figure out why you attach your identity and your happiness to 'marriage.' You need to figure out how to detach from 'marriage' so that you can learn how to be happy without a husband.
