addressing the elephant in the room has made things almost worse...?

addressing the elephant in the room has made things almost worse...? My bf and I were in a LDR for roughly 11 months, which made hiding it easier. I am usually quiet anyway though. Though he never mentioned it when we fought (and I fumble over words even more) sometimes in everyday conversation he'd tease me a bit. It made things quite awkward and I would normally just give up on what I was trying to say. The other day we got pretty stoned, and every time we do my techniques fail. I sit there being a stuttering fool and he's in hysterics. Finally I was on the verge of tears and it was the first time I let him see me get upset about it. I can be insanely sensitive and I didn't want to make this into a big thing but I was so frustrated. He has never encountered a person who stutters and I think he assumed it was something I could control. When I asked him if he noticed before (dumb question how could you not) he said of course. He felt unsure about completing words or sentences for me but that doesn't bother me. He now gets why I am so scared to practice a second language, since my vocab isn't too large and switching words is difficult. Fuck I don't even order my own meals, I just tell him what I want but he never objects or forces me to do it myself. I am glad I talked with him but the thing is, is that now it is even worse. The stress from moving in with him has been enough but now that we have actually sat down and discussed it I put a million times more pressure on myself to just not fucking block. Arghhhh what to do? Would anyone be willing to chat? I know it sounds dumb but hearing someone else with the same problem as me would be nice I guess. Hmmmm.
