It's kind of difficult to give a proper advice on this without knowing much about it.
You need to sort out somethings first if you really like this girl try talking to her that what is it that she really wants and why does she feel that way. Is she asking something that is reasonable or not. If you are willing to make those changes or not.
Get urself a man like this!No such thing as out of the league. You approach her with kindness, honesty, respect, and be upfront with what your intentions are, you got the game. And it also comes down to being confident in yourself, taking the lead and treating the girl right. Sometimes girls say things just to see if you really care about them to not listen to them and prove them wrong that you do care for them and want to treat them right. It's why females are always more creative and smarter than men at thinking. Men are more aggressive, females are protective but weigh in the pros and cons. Not saying all men are like that lol. It's all different situations
