My mother believes in Jesus more than in me

[John V]

Yeah, it's OK for this person to hate on their mother for a prompted remark despite the fact that the mom is driving them where they need to go and financially supporting them. The problem here is Christians calling them out for being ungrateful and self-centered.

As somebody who is unable to have kids, i can tell you it would be my privilege to have had kids and to support them financially, emotionally and with an honest education.

Cool, you can do all that for OP so they don't have to deal with mean ol' mom anymore.
