The hard part is when she texts asking about our D. I ignored them last night and this morning, but I don't know if I should do that. I know she is texting "tell her I love her" or "how was her day" just to get me in a convo with her. Should I respond to her texts about our D?
As ex's you'll generally only get instant communication under special circumstances--awards, illnesses, etc. You learn to live with a delay in non-essential communication. IMHO it's fine not to respond to the above. If your D felt a desire to know how your mom's day was or to tell her she loved her, that's different.
This is part of what you lose when you choose to divorce.
