atsea Fuck right off 
OP. Please ignore that horrendously nasty post. We had two boys with severe reflux. Meds were limited help. Neither of them slept through one single night before they were 2. Going out anywhere, DS1 would not tolerate the buggy or the car seat. He only didn't cry if he was in a sling (or backpack when he was older.)
Obviously the car seat was non-negotiable, so long journeys were very fraught.
There was 3.5 years between them and ds1 had finally started sleeping better (but still multiple wakings a night) when ds2 arrived. He regressed again as soon as newborn ds1's crying began disturbing him in the night...
I know, beyond any doubt, that dh and I would have broken up during this period if it weren't for the fact that we'd been together for 7 years before starting a family. DH and I both knew that who we'd become was not the real us. We were both being tortured by severe sleep deprivation at night and the stress of unsettled and whinging children in the daytime...along with mountains more laundry than any other parents we knew 
Please don't make any rash decisions now. You're quite possibly both still the very same people who fell in love with each other, deep down.
Dh and I have now been married for 19 years, together for 25, and since ds2 turned 2.5ish (he's now 14, and ds1 is 18) I can safely say we are the happiest couple we know. But from ds1's birth, until around 6 years later, was a hugely trying time. We did have happy times, but a hell of a lot of stress and tears too.
Once the kids were more content, everything became manageable again. Don't give up hope. (And do see what other reflux meds you can try. We were never offered omeprazole, which PP's seem to rave about.)
