I've been dating this guy for a little over 3 months. He lives about 5 hours away and works a lot and I'm still in school so we don't get to see each other very often. He usually text me all the time and we would talk on the phone for at least 2 hours once a week. The last time we were together we had sex for the first time. It's been about 2 weeks and ever since then he doesn't text me as much and we haven't talked on the phone once he says he loves me and he doesn't act any different we just don't talk as much but he has been working a lot more. Should I be worried?
