The sense I get from you XW's comments is that she is angry at you no doubt. I find generalizations often a sign of anger and frankly self-pity. By that I mean when someone says to me that I "never" did this or "always" do that or whatever.... more often than not, it is an overstatement that reflects some sort of pain or anger.
In my experience, rarely is it that one spouse NEVER helps another. (Or ALWAYS does this negative thing or that negative thing or whatever). Generalization, in my experience, often are also a statement of self-pity. By that I mean that by your XW stating that you NEVER helpped with anything kinda puts her in a place to be pitied or disadvantaged in the relationship. This is dangerous ground. I try to avoid it in my own life as much as I can because it does not reflect truth. Self pity keeps a person stuck in untruth and blame.
I may be wrong about all of this... I have no idea what your ex is referring to that she feels you never helped with.
Your reply to her certainly admits fault. If she is anything like my X, apologies tend to be no-win situations. If you apologize, she resents that you have done what you just admited to and apologized for. If you don't apologize, she resents that you dont. Either way, in my sitch, my X's inability to MATURELY accept an apology is a sign of an unhealthy person (or immature at the very least).
So.... good on you for rigorously admitting your faults. What she does with it will have to be her business. Frankly, I seldom apologize to my X anymore for reasons I stated above.
It is a tough balance to take responsibility for one's own faults versus getting into the unhealth dance with an immature resentful person.
These tricky balances are the real challenging part of decisons and relationships. For me, I just keep doing my best and try to improve my decision making process each time.
