Summarize:

Seriously. Though your man will claim you're being too mushy, if you're at the "I love you" stage, don't forget to tell him that you love him every day. Show him that you mean it by keeping eye contact and touching him lightly. Remember that there's a big difference between saying "Love ya!" and "I love you." If you want your man to know that you love him, then you should encourage him to achieve his goals every day, whether they are big or small. Being there to support and encourage him the night before a big exam or a job interview will show him how much you care and want him to succeed.  If he's not feeling confident, list all of the things that make him great, and all of the reasons that he'll succeed. If he has a big event coming up, leave him a sweet note to wish him luck. Push him to do something out of his comfort zone. If he wants to train for a marathon but isn't sure that he can do it, you can tell him that he can accomplish anything (within reason) if he really puts his mind to it. Communication is key in any relationship. If you want your man to know how much you love him, then you need to be able to communicate honestly and clearly. Taking the time to check in and make sure that you're on the same page will help your relationship grow even stronger. Here's how you do it:  Don't yell or argue. Instead of yelling or arguing, learn to state your side of the story and wait for a response.  Learn to listen. Communication is a two way street, so take the time to slow down and understand your boyfriend's perspective instead of interrupting and focusing on your own feelings. Be honest. Be honest about how you're really feeling instead of being passive aggressive. Let him know what's on your mind. Pick the right time and place to have a serious talk. If you have something important to discuss, don't just blurt it out in a public place, but wait for the right moment when you both have time to sit down and really have a conversation. You can show your boyfriend that you care by making it clear that being happy is more important than being right. You and your boyfriend need to learn how to work together to make decisions, big or small. You need to learn to factor him into all of your decisions, and to be able to concede some of the time.  Before a big decision, sit down with your man and write down all of the pros and cons of your two plans. Discuss which plan is best overall, and which will make the two of you the most happy collectively. Make sure that both people are compromising. Don't always give in to his needs, and don't let him give in to yours all the time. Take turns, even on the small things. If you picked the dinner location on your date, let him pick the movie. If you want your man to know how much you love him, then you need to learn how to be responsible for your mistakes. If you've made a mistake, let him know how truly sorry you are by saying the words like you really mean them, and assuring him that you feel terrible for hurting him. If you're too stubborn to say you're sorry, the relationship won't last. You should also learn to accept his apologies. You can fume a little bit, but understand that he feels terrible and don't hold a grudge, or you'll never be able to move forward.
Tell your man how much you love him. Encourage him. Communicate like a champ. Learn to compromise. Learn to say you're sorry.
