When you first start dating someone, how do you check to see if they are not married?

You can ask, but they can lie.

Do you just trust them no matter what?

I was the other woman before when I really thought he was single and trusted him.

Now I'm not sure if there are places online to look that up or not, I am wondering if anyone else has ever been in this situation where you thought someone was single and found out many months later that you were the side piece, after wasting a lot of time on him and now having a broken heart.
