It sounds like you two have a lot of problems to work through before/if you get married.

I see some huge red flags here. The bossiness, controlling, and lack of satisfaction with anything you do are huge, huge problems. You are working full time and doing all the household stuff? That sounds unbalanced. Is she doing a residency right now or just studies? Are you supporting her financially?

How do you know what her father says about you? Is she repeating his rude and hurtful comments?

She needs to stop telling you what to do with your time, stop telling you that you need to be X or Y. She needs to accept you for who you are, not who she wants you to be.

I am not sure if controlling people can change. Has she asked if there is anything she is doing that makes you love her less? Does she want to change in anyway to make this relationship better or does she just blame all of it on you?
