Dang, seems like you two are definitely gonna get together at some point. Sometimes I find that while being honest can make a friendship/relationship go through a rough patch, it still ends up being such a relief to vocalize what I’ve been bottling up. Maybe your friend’ll be pissed at you but if you’re hanging out with his girlfriend that often, he’s probably stuffing down his feelings too. Facing the facts can be tough and even if it ends the friendship, you might find you only want to surround yourself with people capable of coming to terms with reality.
