How can I live with this?

I'm (M24) dating a lady(F23) for more than a month right now. We're doing good naman. We're getting to know each other, we are sweet, caring, and nad-develop naman kami sa isa't-isa. I could tell. Meron lang akong isang bagay na hirap akong intindihin kung bakit at paano niya nagagawa. Everytime I make mistakes or we have an argument na masyadong emotionally investing/tiring, she just quickly detach herself and hindi ako kinakausap.

This happened 2 times. Nung una, early days palang ng pag-uusap namin. I made a mistake, she stopped talking, I won her back and we still continued. Now it happened again, this is a bit less intense naman sa nangyari nung before. We had a misunderstanding.

Ngayon, hindi na naman ako kinakausap. Despite our dates, pag-visit niya sa house, intimacy, our vibe and connections, napakilala ko na siya sa family ko. Why is it still the same? Bakit parang wala kaming napag-samahan to hold her against detaching herself from me? Kapag ako naman yung nagagalit or nagsisimula ng argument, I always choose to communicate with her kasi she's always above those feelings and arguments. Pero pag ako, ekis agad? I'm wondering if dapat ba meron pa akong ibang ginawa? Or it's not me that's the problem?
