If he had a vasectomy done why is he lying to women that want kids?

We've been dating for 2 years and he seemed like a normal guy. He kept promising about a future and kids. Then just recently this November he was going to ask me to move in with him.

I don't know if destiny worked in my favor but my parents and I got infected the day before Thanksgiving Day (mild symptoms though) so I we had to quarantine for 14 days. Fast-forward to mid December, I find out through one of his former ex girlfriend that he already had a vasectomy done before and it's not the first time he lied to girls about wanting a family. He wants girls to move in, lied about wanting kids and never telling them he can't have kids.

Needless to say I broke up. I find that cruel. Why isn't he with other women that don't want a family? Why is he lying to us? Why is he wasting our time? That's 2 years of time waste I'll never get back. 2 YEARS.
