I know it's hard to cut out the I love you's. It something I did very, very early and it was extremely HARD. But I also didn't want to push my W away. They already know this, but when you say it, it reminds them they don't feel the same way RIGHT NOW.
Sounds like it may be helpful for work on your GAL. I can speak from experience that it will do wonders for your mental health.
