Student Exchange Programs

Recently, my boyfriend, whom I’ve been going out with for almost a year, hasn’t been giving me as much attention as he used to. He has a new, foreign exchange living with him and all he’s been doing the past month is hang out with him. I know, he has to bond with him and what not but is it too much to ask for him to at least call me once a day and talk for a few minutes? Before, we would talk on the phone every night before we go to bed and either spend time together at school or go to eachother’s house. Now, if I’m lucky, he’ll call me within 3 days. He also is on the football team so he’s busy with that too, but even when he doesn’t have football he won’t call me for just 10 minutes. I confronted him about the way I felt and he got all in my face about me being selfish, which made me feel worse than I was already feeling. After a long talk, he promised he’d start calling me more often. However, he hasn’t. He is still spending all his time with his exchange student and blowing me off. I feel lousy and when I do get to talk to him on the phone, I feel like I’m intruding on his fun. Am I being selfish?
