I work in a freelance creative industry (TV production) where I will be contracted on a project for a finite amount of time. My current role is 16 weeks and I'm 6 weeks in. I'm self employed and very very pleased to have the contract as sometimes I go a couple of months between contracts and have to budget to make the money stretch the whole year. Being self employed I don't get holiday pay or anything like that (just demonstrating how precious the work is to me.)
My role involves being paired with another freelance professional and the two of us work together in an edit suite reporting to senior members of staff but essentially it's just the two of us for the vast majority of the day.
This job was the first time I had met this guy, usually you work with people on the circuit but I hadn't come across him before. We get in great, he's 15 years older than me but seems young in his outlook and we have enjoyed chatting and having a laugh at work.
He told me about how he met his wife online and got her pregnant on their second date and now they're married and their child is about six months old. FWIW I live with my long term partner. He would sometimes tell me how his wife and he would argue but always in a jokey tone, he probably did share too much but not just about his relationship about loads of stuff - mostly just idle chat as we worked.
This evening I have received a WhatsApp from his wife (must have taken my number from his phone) telling me to stop calling him, he's a married man and he has a child and I need to back off and stay away from her husband. I had a missed call from him yesterday evening, called back assuming a work thing and he didn't pick up. Wasn't mentioned at work today I didn't think anything of it.
What do I reply? I don't want things to be awkward at work and don't want to put my job in jeopardy by giving the impression at work we are not being professional. We are doing a good job with good feedback. Should I message my colleague and tell him?
