He doesn't go a day without talking to you in some form of communication. Whether he calls you, shows up at your door or sends you texts, he wants to know how your day was. He's genuinely interested in what you have to say and even if you've done absolutely nothing, he wants to hear about it. If you're ever going through a rough time and he's making an effort to make sure you're okay, even if he isn't physically with you, then he wants to be your lobster.
