I had two longest relationships, they lasted about 4 months. My first ex whos hearing became addicted to drugs while we were dating, things gotten worse in the last month. He dumped me out of blue and for no reason. My last ex, hearing too, we weren't serious together but I think he dumped me for another girl.
My longest relationship with a deaf guy... Gee, I don't know... I think 3 months? But we never saw each other during 3 months long distance relationship lol. We agreed to stop dating cuz of that.
