Even if you are dating someone, calling them can still be nerve-racking. Just remember to be calm. Since he is your boyfriend, you don't have to stress as much, even if the relationship is new. You know he likes you and should be happy to talk to you on the phone. Make sure you're in a comfortable and quiet place. You are more likely to be relaxed and will be able to talk longer without interruption. If the last few times you talked were filled with silences, think about things you want to know about you boyfriend before you call him. Is there a game you know he just bought that he's been playing? Ask him if and why he likes it. Try to remember small details that he's brought up when you were last together, such as "How did that paper turn out that you were working on a few days ago?" This way, he knows you pay attention to him when you're together and knows you care. This is especially helpful if you find that you've run out of things to say the last few times you've been together or talked on the phone. This doesn't mean that the relationship isn't working, but it could just mean that you're both shy or that you two don't know each other that well yet. Don't wait around for him to call you. Just because he's the guy, that doesn't mean that he is the one initiating everything. Calling him lets him know you're thinking about him, that you care, and that you are still interested in him. Make sure you don't call him too much. This seems clingy and you don't want to suffocate him. Keep it balanced. Don't be afraid to ask personal or difficult questions. Ask him what his future goals are, what his life's ambition is, or what he is most scared of in the world. Try phrasing it in a way that makes it open ended for him to fill in as much detail as he wants, such as "I know you're majoring in civics. What would be your dream job?". This lets him know you care about him on a personal level and that you want to know all the different parts of his personality. Don't ask him where he thinks the relationship is going or...
