Bf has real bad breath. I’ve plucked courage up and told him about 4 times now. Told him again and he gets upset about it. Starts giving me attitude and saying why haven’t I told him. But I have?! I understand he prob feels embarrassed but I can’t live like this anymore. We don’t kiss, sex is affected. I just can’t get in the mood because I can smell his sour breath. I feel bad for saying but know I shouldn’t?
