Thanks I'm finding this all very helpful, to get an idea of the general take on whether it's normal or not.
My husband thinks that if I'm friends with males at work that there's automatically something else going on, some other agenda.
Though there is some historic specific 'stuff' that is making him worry so I do understand his worries. In the past he found a message from me to a friend saying there was someone I fancied at work and that person was someone who was included in a group of people I went for drinks with after work. But for me, saying I fancy someone and acting on it are two very very different things. I have no desire to be unfaithful, I'm just not interested in taking any action, so the fancying those years ago was kind of an annoying (yet sometimes fun to daydream about) thing.
Annoyingly at my last workplace some bloke got completely the wrong idea and thought that my friendship meant I was in love with him and that I wanted to have an affair. He was quite a peculiar guy, a bit odd with women. To cut a long story short, I told my husband all about this guy, about his messages to me and we agreed that they were inappropriate and that I had to tell him to go get lost, which I did. I also left that job.
Because of the experience above I do feel a bit confused about whether it's ok for male and female colleagues to be friends, or whether all men just automatically assume a woman is 'up for it' if she shows any interest in having a friendship or going for a drink. The creepy bloke at my last work thought that, and my husband thinks that... so maybe that is what all blokes think?!
Sadly my husband just doesn't trust me, though I have never been unfaithful and never will.
