Try taking a deep breath. Relax. I know I've done all the things you are doing. Back off the texts. When you do, or if you do text something you regret, say nothing. Don't apologize or assume that you "messed up" by texting it. Confidence. You will backslide, we all do, but don't shine a light on it. I really think that my H doesn't even find it annoying/upsetting/insert whatever mindreading I'm doing UNTIL I mention it.
You are so new in your sitch. Really work on 180's, GAL, etc. Once you start to detach, you will know when you are done standing. Right now your emotions are all over. This stuff is so hard.
