My girlfriend expects me to provide everything

I am 26 years old and have been dating my girlfriend for almost five years. Initially, our differing views seemed significant, but various meaningful experiences have brought us closer, despite numerous breakups and reconciliations throughout the years.

She possesses a practical and strong-willed nature, which has inspired me to strive for betterment. Yet, she consistently expects love and care, which I have willingly given. Gradually, her demands have escalated from costly gifts to luxury items, forcing me to economize severely to satisfy her. When my career faced challenges, she expressed disappointment and distanced herself from me.

Recently, we paused our relationship and later attempted to resolve our differences. She admitted that we have several incompatibilities, even suggesting that I have not met her sexual needs. I responded: "I understand our differences and that I haven’t provided the lifestyle you want. But I have tried—whether it was a new handbag, phone, or funds for cosmetic enhancements, I have attempted to meet your demands."

She replied to me that she might stay if I could continuously meet her expectations, which she believes is a man’s responsibility. This made me recognize more of her shortcomings than qualities.

Given her perspective, I believe our differences are too vast for compatibility. I need a partner who understands, shares, and accompanies me through life’s journey. In contrast, my girlfriend’s high expectations and words have diminished my affection for her.

Should I persist in this relationship, or end it now so we both might find partners who are more suited to us?
