Time for you to start posting and journaling on FB how well YOUR life is.
I agree with Bond! I started doing that from day 1 of my GAL efforts and W has made a couple of comments about what I have posted. So I know she checks it and I know that it makes her curious.
Don't take it too far though. Early on, I posted a pic of a couple of new friends that I had met at a party. One of the friends was a fairly attractive woman. Now this was when my W was still had a ton of vitriol towards me, but she commented very sarcastically under the photo "nice". I know that it bothered her, but not in a good way due to my particular situation. My point is, just use it as a way of documenting how you are GALing. It can be used with great effectiveness and provide your H a brief glimpse into your life.
