How do I work things out with my INFJ gf?

Thought this would be a good place to get some feedback.

Have been dating my 32F GF for 10 months. She's very attractive, smart, kind, and we have a lot of the same values and goals for the future.

I am a very caring and loving boyfriend and constantly get her little surprise gifts, flowers, assure her of my love, plan all of the dates etc. but every week or two she gets upset at me about something I said or did. All of these seem very trivial/minor to me (why did you say this in that way, or why didn't you do this, etc) that in my past relationships would never be an issue but to her it upsets her and we always have to have long stressful conversations to heal all of these arguments. We get over something and then there's something she's mad about right around the corner.

I really love her but I am at a breaking point and can't keep continuing to feel like I'm walking on eggshells everyday and that everything I'm doing is wrong and everything has to be such a serious conversation.

Any tips here? I'm at a loss.
