Give your partner one appreciation every day.  So often people tell me they don't feel appreciated by their spouse. Tell your partner how much you appreciate something nice or thoughtful he/she did for you today.  Or, tell him/her something about their personality that you appreciate (like their sense of humour or their dependability.)  Appreciations help us feel emotionally safe with each other.

Sexual intimacy is an important part of a relationship.  If you find you are too busy or too tired for sex, planning a date for sex can help. It gives you something to look forward to and prepare for.
Take turns planning the date in whatever ways you both find romantic and sexual. B.Fontana PhD
