Why do you think you were backsliding? Was it because of the texts or because of your reaction to the texts?
We are married to the same guy right now. They are struggling with the independence. I had yet another run in with mine this morning over the same issue.
You need to do this right now because you are trying to get yourself back. You cannot worry about his reaction to it. Easier said than done, I know because I struggle like you do. But you still must go on. He is going to continue fighting you on this. So, you must be prepared for it. I figured mine would back off, but he is just getting worse. The thing is, there is a lot of doubt in our minds as to why they are acting the way they are (at least for me) so our only choice right now is to keep going. Set your goals and continue keeping your eye on that goal.
(((big hugs))) I know this is so hard. We all know this is so hard. You just continue to do the best you can. You are doing so well and you know what you want.
