Me and a guy friend of mine, who also happens to be my HS classmate, have been spending more time together for the last few months. I would say at this point that he's a very close friend but don't want to assume anything more than that. Anyway, after hanging out with just each other for so long, recently he's started bringing along a guy friend of his, who also brings along a girlfriend or date I'm not sure, and ever since it's been an outing of 4 people instead of just us 2. I don't know what to make of this, and a part of me wonders if maybe he's trying to show in an indirect way that he doesn't want just the two of us hanging out anymore or what. But really, what does it mean & what if it continues in the future?
