Does he really love me????(please answer this question i need help)?

my name is brianna and i have been with brian for about 6 months now. i am so in love with him thats why i need to know if he feels the same! he does not have a car right now so it is hard to see him but we talk on the phone everyday. he tells me he loves me all the time. but then when he gets around his friends he changes, he acts like he doesnt want to talk to me. i am a good women i would do anything for him and he knows that. i dont think you can pretend to want to be with someone thats not even having with you. there has to be something there.RIGHT???????? please help me
