I find it interesting to read that some married men admit to feeling uncomfortable around single women. On one hand, I admire their honesty in actually admitting to this. On the other, I find it really sad.
As a single woman - actually, single has nothing to do with it - or being a woman…so I’ll start again…As a Catholic human being, I believe I have a responsibility to respect the institution of marriage; to act sensibly (as in behave and dress in a non-provocative manner) around married associates and to definitely, definitely not try to seduce married men, or to undermine the sacremenmt of marriage by making derogatory comments like refering to it as being ‘trapped’ or similar, as a way of retaliating to silly, insensitive comments about my being single.
However, I am
not responsible for the insecurities of anyone else, married or single. I trust myself; my married male friends and colleagues trust and respect me too, which is why we get on so well. I like meeting people, so when I meet wives and girfriends I make every effort to be interested and polite too. Generally, this approach works fine.
I find it incredibly insulting when married or otherwise attached men feel the need to make it clear they are married / not interested almost immediately on finding out I am single - usually in crushingly un-subtle ways

or when they bring their wives and girlfriends to evening functions or open days and their behaviour towards me changes. It doesn’t happen often, but when it does, it is hurtful.
Sometimes I feel you can’t win - if you dress down and act like ‘one of the lads’ you are not ‘making an effort’ - you are ‘un-feminine’ or at worst, a suspected lesbian. You are treated either with pity or something approaching revulsion because you must be so clueless and desperate that you might misconstrue anything approaching a smile as an invitation to pounce:eek! (I need to carry a card in my purse that says ‘Not a marriage-wrecker - Not a lesbian: I am a Catholic, so adultery and homosexual acts are not on my to-do list! Now that’s established, can we move on?’)
On the other hand, if you dare smile too much, or wear something a bit femninie and floaty (not that I could get away with too much at work) or even take the banter a bit too far - you are seen as ‘asking for it’ or ‘up for it’. The problem is that because we are all different - what some men and women percieve as flirty behaviour is what others think of as friendly banter.
