My fiance saves rather than helps with finances

Is it unfair or am I being a little much, when I am constantly paying for child related items when my fiancé gets to ‘save’ said money yet has none when I’m completely down to my last pennies.

He purposely keeps money from me when he has more than I do. He’s unwilling to split bills.
It feels very one sided…

Is this enough for someone to feel the need to leave a relationship

4 years and 2 kids.
It was a fast relationship

It is unfair. Why are you spending all your money for the children you share but he keeps his??? No, he needs to help.

Yea this is called financial abuse.
And yes you can leave without feeling bad. Don’t put up with that
