Need advice

Selena

So me and my boyfriend want to move in together but the only way that can happen is if we get roommates so his first thought was he friend and her boyfriend but this isn’t just any friend this is his friend whom he’s been friends with for more then 4 years and who he currently trust more than me. I don’t know what to do I told him it was fine because he thinks I don’t trust him .. I want to feel better about the whole situation but don’t know how and don’t know if I should be worried or not.
