My current girlfriend tips the scales at 98 pounds. 5 foot one inch. But she's got a big girls mouth. Sometimes I sneak up behind her and twack her earlobe because I can out run this one!..
My lovely wife is 5'4" tall, and
now weighs about 150-ish, but when we met, she only weighed 90lbs at most. I could fit my my two outstretched hands around her waist, wrist only took one hand to circle. She was badly, severely, underweight, almost "Karen Carpenter"-like. pretty near 0% body-fat percentage.

Her then-husband had a lovely habit of drinking up his paycheck

, and if he bought any food for either of them it was a mistake on his part or a bit o'theivery on her's. He realized our relationship developing and was happy for us both, oddly enough. He tried to get her to leave, I tried to get her to leave, but she had been so badly brow-beaten by him for so long her self-confidence was almost completely gone.
I finally, metaphorically anyway, dragged her out his door, he pushiing her just as hard as I was pulling, she resisting. She was terrified of any change. Once I had her out, the job of building her back up physically was much easier than emotionally, but I fed her and she slowly gained weight, till she was almost "normal" again. I also had to rebuild her ego, and self-confidence, both of which I think I have managed, after almost 25 years together now
This all was, naturally, after I divorced my then-wife, who had gone from almost 400lbs down to 175, due to plenty of meth use, rather than getting food for the 5 kids. I finally opened my eye, so to speak, to what she was doing. I hadn't
wanted to see it, so had been blind to it. I cut her off, notified CPS, and left. They took the kids, so she had nothing left. No money, no food, no kids to do her biddings, nothing but her several boy-toys she had been allowing to use her physically for several years. They didn't provide her anything but...umm...you know...
Anyway, we got divorced, she moved to Texas, and good riddance.

I moved back into my house, worked my tail off cleaning it up and disinfecting/debugging (literally) it, got the kids back, and finally married my NOW wife
There was a short episode that nearly led to my self-induced demise by 9mm means

, but thanks to my lovely wife, she pulled me back from THAT edge, thankfully!
The kids grew up and left home, and the lovely wife and I moved up to Oregon here. We both have never been been happier in our lives, my physical illnesses not withstanding
Sorry for the excessive rambling, I just want to show how her and I have been through a LOT together, and apart, but
NOW are finally happy together
