Good idea, Autumn. Wouldn't be a bad idea to -- at least once -- reply something like "Well, it's safe to say that we both have a much different interpretation of what we discussed and agreed to, but okay" (or some such) -- just in case he is saving these for legal purposes.
Also wouldn't be a bad idea to occasionally try to "diffuse" with something nice to one of his texts, like "I can see you're trying; I do hope things eventually work out for both of us" or "I'm not your enemy, despite what you think -- I'm just trying to do what I think I need to do right now, what's best for me and the kids", etc.
