Why would a man lie about still being with his girlfriend during conversations when he isn’t?

Anonymous

There is this man I met at work who I have worked with for years now.
He is 49 and I’m 30.

We got a lot closer over the last year or 2 where we began talking more outside of work, flirting and messaging a lot. We have a lot in common and we get on very well.

He told me he liked me a year ago now at our Christmas party last year. When we returned to work after the holidays I found out he had gotten back together with his ex. I was disappointed but we remained friendly and I backed off.

Then gradually he became distant, the messages stopped and he stopped talking to me as much which I understood and any time we did talk he would mention his girlfriend all the time.

We have the same boss and we were having a meeting and my boss made a joke about him being single and he replied oh I’m glad I got rid of her bla bla bla it’s been the best few months of life being away from her because of x y z….
But he told me he was away on holiday with her when he actually went alone and he always asks me about my weekend plans and he always tells me me & Vikki are doing this and that.
I asked our mutual friend about it and he confirmed they broke up in the summer. And he mentions her by name unless he’s dating someone new with the same name …..

Why would he continue to lie about that to me during our conversations?
