My wife talks about divorce and walking out over small fights. Should I just concede defeat?

definitely not just a small fight, when a women say divorce, that's means there is a lot of small small things combine, and make her very stress or what, u definitely can't find the answer and thats very common to guys. Buy something she love, like when me and my husband got fight, although we never talk to each other, but he will order food delivery for my favorite bubble tea, and from there to start the topic, calm down and talk to each other. If really not suitable, both of you are deserve happy life, not only happy marriage!
