"Man must provide" is kind of an irrelevant issue here. This is an unhealthy relationship. Y'all aren't on the same page, don't have a good foundation of communication, you don't have the same goals or expectations. You have a lot of drama and unhappiness. It's ok to just move on. Find someone who suits you better.

Who provides is up to the people involved in the relationship. What matters the most is that you agree on the setup, not who does what. If you want someone who is an equal partner financially, date people who expect to be equal partners financially.
