How to call out a liar?

Ok, as yall know my SO is on this app, so it's anon 😆...

He has said that he never wants to be married but he has said the order of how he would like it to go.

He has said, he'd like to have a kid first, own a 4 bedroom house, with two bathrooms, basement, 2 acre lawn, ect ect.... And then be married....

That won't happen. We cannot afford that.

I know 100% he's bull💩ing me.

How do I bring it up again?

How do I call him out?

What do I do from there?
