Yes, it’s reasonable and entirely within the realm of normal human feelings to not want to go to bed alone while your boyfriend continues a conversation with your male roommate. It is reasonable and normal to feel upset that this desire wasn’t implicitly obvious to your boyfriend.

But the typical response to a minor misunderstanding like that is to make the communication more explicit with a simple request that the boyfriend come to bed and share that you felt upset about it, trusting that your caring boyfriend will feel sorry, make a note and try to do better next time. Not to lead with accusations of ill intent and quickly escalate to a full range of emotional manipulation and threats of physical violence.
