Marriage is hard work and both people have to be willing to work on it or it doesn't exist.
Don't hurt the one you love because you don't know what to do.
Read a book. Pray. Go to a counselor. Talk to each other!
Here is a great book for everyone - single, happily married, or having troubles

Read it, Do it.
