Yep I agree totally. My DH works at a place with around 15 women (and just 2 other men,) and they all do different shifts. They do clash sometimes though. One woman (I will call her Carol,) was always over familiar with my DH (who is friendly with all the women and men, and likes a laugh and a joke,) and she started buying him gifts from her day trips, and weeks away, and bought him gifts that related to his hobby etc...
She spent more on a Christmas present for him one year (around 2016,) than I did. I felt upstaged and angry and upset, and DH couldn't see the harm in it, said he has zero interest in her, and said I was over-reacting. He even started buying her gifts too as she was his 'friend...' Didn't buy any other colleagues anything though. 
And on the few occasions she saw him out of work (with me) she would ignore me. And on facebook, (he had her as a friend, I did not,) if I posted 25 pics of a day out and tagged him in, 10 scenic, 5 of him, 5 of me, and 5 of the 2 of us, she would only 'like' the ones with just him on. Sent Christmas cards with only his name. (Not mine, and not our childrens names.) When we popped into his workplace on one of his days off, she would flirt and attempt banter, and playfully push him.
And she said one time 'they think there's something going on with us don't they?'
DH said 'do they? who's they?'
She punched him lightly on the arm and said 'oh you! I know I shouldn't speak while wifey is in earshot, wink wink.'
I was fuming back at the car, and said to DH 'why the fuck did you not tell her to stop trying to make out there's something between you?! So fucking disrespectful toward me!'
He just looks like 
It wasn't until our DAUGHTER who was in her early 20s, at the time, had a go at him (when 'Carol' got him a £75 gift for his birthday.) She said 'dad why the hell is this random single woman at work constantly buying you expensive shit all the time, and why are you taking it and not telling her to stop?!' She was angry too, and could see how upset I was by it all.
DH did nothing to encourage her (AFAIK) and nothing happened between them (AFAIK) but he did nothing to DIScourage her either. Until our DD spoke up, and told him to get a fucking grip and tell this woman to piss off. I don't know what he said to Carol, but she left the place not long after! Not seen her since. This was 2017.) She blocked him - and me - on facebook too LOL! Good riddance.
But yeah tl'dr, some OW are scum, and DO chase after married men. Most married men are flattered by it, and amused, and seem to enjoy the attention, and it's double bonus points of their wife is threatened, and jealous, and upset. Don't play with fire. If this had carried on, it would have finished our marriage. As I said, it was SO disrespectful to me. Shame it took our fucking young 20-something daughter calling it all into question, and telling DH to make it stop!
As has been said, of COURSE the man is to blame as well in any given affair, but the OW is 50% responsible, and is a piece of shit too IMO. Fed up of this 'OW doesn't owe you anything' shit that always trotted out on here, because some women DO make a beeline for other womens husbands. They act like he is some fucking prize to win, and she is better than the wife because she has made him stray.
Very rarely leave the wives for these desperate OW though do they?
