She trusts her parents over me

My girlfriend and I want to get married a few years from now, but her parents want us to wait because they think I need to be financially secure first. I have a good job and enough savings, but their idea of security is different from mine because they are more well off than my family is. I don’t know how my girlfriend really feels about this because she only accepts what they say, and this bothers me because it feels as if she has no faith in me or my abilities. I want her to support me and believe that I will be able to earn more money in the years to come. She says she loves me and wants to be with me, but won’t go against anything her parents say, which makes it hard for me to believe anything she says. What should I do?
You can give her time to try and reconcile what she tells you with how she feels about her parents and their wishes. She has to maintain a balancing act and probably needs you to acknowledge this as she navigates relationships with you and her family. It also makes sense to try and spend time with her parents, to better understand where they are coming from and why they feel the way they do. They obviously have their daughter’s best interests at heart, as do you, which means you may all just need to have a conversation about where things stand and how you can all arrive at a compromise that works for everyone. Don’t give up on your relationship just yet, because this isn’t going to be easy for you, your girlfriend, or the parents involved.

I want to be nicer to my girlfriend, but she always provokes me and starts arguments that end up with me making her cry. How do we get out of this habit?
If you really want to do something out of love, you should be able to without holding her responsible for anything.
