Why do men cheat and lie?

I recently met a guy. Things were going well at first until he ghosted me out of nowhere. It turned out that he lied to me about everything in his life- his job, his relationship status and where he is currently residing. He told me he was going to working here for a year and was apparently the head of department in an American pharmaceutical company. But he was actually just a manager in his home country. At the time, he was also on holiday with his wife (who is a local) and was visiting family along with her. I also find it disturbing that they had a baby just last year.. and our first date was just 4 days after his wife's birthday. I am hurt and feeling all kinds of emotions. I just can't understand why would anyone do this to their loved ones
