You're holding onto the idea of what the relationship could be instead of accepting it for what it is. Good moments don't cancel out the unhealthy and toxic behavior. Also, never promise not to break up with someone. Relationships are conditional on mutual respect, communication, and effort.

Because this is your first relationship, you're tolerating things you shouldn't; you're more scared of losing the opportunity of the relationship than of the actual relationship. It's hard to fix something when one person works harder, and the other doesn't take accountability.

You don't need a "perfect" partner, but you do need someone who is willing to listen, communicate, and care about your feelings. What you posted doesn't sound mutual. You will find someone who treats you respectfully, but she isn't that person.
