Every relationship goes through its ups and downs. There are times you may feel confident in being a couple, while there are days one or both partners may express doubt or concern about being together. Showing your boyfriend in practical ways like compliments, surprises, love lists and listening that you are committed to your relationship and want to be together will reassure him that you care.

Continual Compliments

Convince your partner you care about him by praising him in front of others. Saying nice things about your mate in the presence of friends and associates is one of the most supportive things you can do, says psychotherapist Barton Goldsmith in the "Psychology Today" article "10 Ways to Get and Give Emotional Support." Try saying, "You are always so generous with me" or "I love the way you hold the door open for me." When he hears you saying kind words about him in front of others, your boyfriend will feel good about himself, and it will show him that he has no need to doubt your relationship.

Unexpected Surprises

Surprise your boyfriend with a love treat to show him that he can have confidence in your relationship. It could be as simple as writing a card to say, "I appreciate you," or buying a little gift that has a personal meaning. You could offer to do his laundry or clean his dorm room. Even simple actions can speak volumes, especially if your partner has had a difficult day, says doctor of psychology John Grohol in the "Psych Central" article "Six Ways to Show You Care."

Love Lists

Reassure your boyfriend of your affection by creating a love list to communicate why you believe he is special. Author and clinical professor of psychiatry Laura Berman says in her Oprah.com article "Dr. Berman's Relationship Homework Assignments" to write down five things you love about your partner and have him do the same. Then, sit down and share your lists with each other. Berman says that this exercise will often help to alleviate jealousy and insecurities in a relationship.

Listening Ears

Take the time to sit down with your partner and really hear what he is saying. Knowing that you are being heard is very nurturing, says Goldsmith. It is also the best way to heal old wounds and prevent misunderstandings. Set aside a time when the two of you can talk without interruption. You could try a listening technique called paraphrasing by saying, "What I hear you saying is..." or "When you said [blank], this is what I heard. Is that right?" As you intentionally listen, you will help to put your boyfriend's mind at ease and remind him of how much you care.
