Marriage isn't just trying to survive. It is more meaningful then that. Marriage is about making sacrifices for the one that you truly love.
When they are sick, you make time away from work to take care of them. If your partner is upset about you going out a lot and not paying attention to them, you should give them more of your time. Doing small things can be a big help and make the relationship less dramatic in the sense of arguments.
Make sure you let your spouse know how much they mean to you each day and never take them from granite. You never know when you will see them again and this is why it's so important.
Communication skills are one of the most important aspects of marriage. If you can't communicate with your other half, the relationship is doomed. Try talking less and listening more. Or if you are someone who talks more and listens less, it is time to lend them your ear. Maybe your spouse wants you to listen to them so that way you'll know exactly how they feel about a certain situation.
