If your boyfriend is not keeping in touch with you as often; breaking dates; tells you he is going out with his friends one too many times; doesn't explain what he has been up too during the week (no communication); if you are in a sexual relationship and he isn't up to having sex with you there is a possibility he has lost interest in you. Communication is very important so if you want to know you should ask him right to his face and discuss whether there is anything going on in your relationship. He may be depressed; tired from studying and perhaps working part-time so don't jump to conclusions too quickly.
