About a month ago, my boyfriend broke plans to hang out with a buddy, instead he came and picked me up. We have been dating for a year. His friend called (male) and he was hestitant about picking it up. After telling him to just pick it up he did. I thought at first this conversation was going to be short, i was wrong. I sat there listening to his responses which consisted of my boyfriend talking to his male friend in such a sweet voice as he kept aplogizing endlessly for changing plans with him. It was that moment where my female intution kicked in. I felt my stomach turn and thought something wasn't right; As if he was keeping something from me. Usually when guys change or break plans with other guys it's a quick, no big deal converasation which was what i was expecting but did not at all hear. The conversation took on a few minutes and all he kept saying was "i'm sorry, I know, ok, you're right."

I brought up how uncomfortable that conversation was and why his friend needed such consoling. He responded by saying he doesn't really have any friends except for a girlfriend, his parents passed away when he was really young and he was his only male friend so he felt obligated to him. All they apparently do together is smoke pot. I would have normally overlooked the entire situation but something just hit me by that conversation and because of that i've been finding out for myself what really is going on. So i would check his phone calls and the he would be on there several times a week. The night's i'm not over apparently his "friend" is. Should i be this concerned or is it nothing to worry about it. I love him and the thought of this devisates me. We're planning on marriage and kids soon, so if anyone has any advice please please help. I can't talk to anyone about this especially my friends- it's embaressing. Thank you for time.
