Make a decision about how often you want to correspond with your partner. For example, deciding you are going to talk on the phone at least once a day.
Figure out what you and your partner's love languages are! You can use these to better connect with one another, especially if you commit to using their "love language" a set number of times a week.
It may help to write a contract to meet this goal, where you and your partner agree to be forgiving with one another. You can also be more specific, agreeing to not go to bed angry with one another.
