TVT Help

Hey, my name is BonkerZ (some of you might remember me from WoL). I used to be really active here as a top masters terran player back in the day, but I stopped playing. I just started again, and I can't for the life of me win a TvT the 1 base reaper bullshit is so annoying, and I honestly don't know the best way to handle it. TvT is the only matchup im losing at High diamond / Low master. Anyone have a build that I can use to just expand defensively and safely against reapers?
