Sherman recommends finding creative ways to show affection, whether that be "just because" gifts and care packages, old-school love letters, poems, flowers, or tapes.
Research shows that couples who do novel things together are happier, so surprises are a positive.
The first thing to recognize, says Sherman, is that every person is different.
"When two people are together, some people don't like to get texts when they're at work.
Says Sherman, "Couples have different boundaries but if you're fine with surprising each other and/or meeting each other's friends when they do visit, they won't feel like this outlier in your life or that you have a secret relationship." Going to bed angry is a bad enough feeling in itself, but couple that with hundreds or thousands of miles between you and disputes are instantly amplified.
