Yeah, women gaslight. You should meet my mum!
XH#2:
Was in a car, parked in the middle of our road, at midnight with a woman. He'd just phoned to say he was nearly home from a work thingy with a male colleague. I went up to the car, the woman hopped out and he drove off. I asked the woman if she knew my husband, she said "No, I'm just visiting a friend" - next door to us. I went back in, there was H, insisting his pal had just dropped him off on the corner. I tried to pursue this with him, he just said I was 'pathological'. I ended up thinking I must have not seen what I did see 
Frequently disappeared at parties. One of a certain few women would disappear at the same time. They'd be gone for hours. He'd tell me they'd been chatting at the end of the bar or some such, and only for an hour. Again, I doubted myself as much as I doubted him.
Told everybody he was single! We knew a lot of the same people; everyone knew I was married, but practically died of shock if I happened to tell them my H's name. Again, I was imagining it due to my (supposed) extreme possessiveness - he said. I actually bought books on how to become less jealous. Dickhead me.
Regularly 'lost' his credit card shortly after overstretching it on a night out. He was the most generous man at the bar, but didn't pay for what he'd bought and cadged off me for the rest of the month. OK, that's not strictly gaslighting, but I certainly felt
when I figured out what he was doing.
I was going to offer some more gems from my two delightful husbands and my insane 'best friend', but I'm getting too angry!
