Whhyyy do I (36F) keep sending texts I regret?

My husband (37M) & I get into text fights and everything gets misunderstood and it makes everything worse.

It's like I can't express myself in person because it's too uncomfortable but then via text I go unhinged. I say what I mostly mean but I say it in crummy ways, then he gets defensive and then I do and we spiral.

This happens with our friends and family, too.

I'm considering starting a service where we have a therapist or communication specialist (anger management person?) rewrite them for us, or tell us how we might be perceived by the other person? Maybe even just acknowledge what we're feeling and celebrate that we didn't send it?

TL;DR

Has anyone started a service to rewrite texts for us yet?! Would you use it, too?!
