13 yrs ago my ex-husband bypassed my kitchen vent in an attempt to "fix" the drains, could this be making my family sick?

He not only bypassed the vent, instead of you usual U-trap it does a loop-de-loop, then he cut a hole through the bottom of the cupboard and the floor. Instead of the pipe going through the wall like it should it goes through the floor at an angle to the top of the cleanout just above the basement floor, out the other side of it across the basement floor supported by bricks for about 10-15 feet then connected by an elbow then it goes about another 10 feet with a 45 degree elbow into the floor drain.

What a cobbled up mess! He just left me a year ago and would never let me fix it the right way, I should have left him over that ordeal 13 years ago!!! So tired of everybody telling me my house smells!

I believe you’re talking about an “S trap” under your sink which is not a permitted type of plumbing installation. Water that is filling the downstream of a vertical portion of the S trap is often responsible for siphoning and sometimes loss of trap seals. 
This means that water flowing down the pipe will create vacuum and suck all the water out of the p-trap section. That little bit of water inside the p-trap creates a seal which blocks sewer gases from entering your home.
S trap installation is not permitted, creates siphoning and loss of trap seals
Missing plumbing vent is another serious issue and taking care of the vent and the “S” trap would most likely take care of an unpleasant odor in your house. Unless there are some other plumbing issues you might not be aware of…
