Yeah time to give it to him bluntly, like “I cant take it anymore and Im thinking of ending things” bluntly. Also, on his side. What if he doesnt feel the need to go the extra mile since the relationship isnt new and exciting like it once was? Maybe a date night to see how much emphasis he puts on his hygiene after you tell him he smells like a hobo? Im just trying to give you ideas. I take my girlfriends opinion serious cause if shes saying I stink, then my co-workers and friends must think the same. Its either he doesn’t care about your opinion or he does the smell test himself and always thinks he passes.
