Read that Five Love Languages book by Chapman - very easy read - talks about the different ways people express and like to receive love - and how if you aren't speaking your spouse's "language", they can't hear you. Deceptively simple but powerful concept. For instance, the guy who expresses his love by Acts of Service - washing your car, bringing you coffee in the morning - married to the woman who prefers to receive Words of Affirmation. She's mad because he's not saying ILY all the time and sending her gushy cards, while he's showing his love every day with his actions and she's missing it.
