I myself have issues with replying to email and texts texts. It is not that I ignore them. It is that i can’t keep them in focus. If it is in appropruate to answer at the time they fall into the aabyss. I have used tags and unread markers but some that is not always possible like when driving or working with others.
MMy wife of ten years now still gets frustrated with my missing comunications and not remembering facts. She has learned to put things in my google calendar, send another text asking for confirmation, or just call. Basically if this hurts you and the extra work is not worth the aggrivasion, break it off. Also if you don’t get your needs filled break it off. Make sure you are happy first.
