I think it's healthy to take breaks, it can get a bit too much sometimes and as I always say in my IC sessions, I need to LIVE my life to allow it to move forward. Sometimes I feel like I'm holding my breath and waiting for changes to just happen.
For me, SI keeps me stimulated and is a go to. It really replaced my AP. A place for me to go to and share my thoughts and feelings and to try to understand wtf happened. My infidelity doesn't feature much in my M as my H has convinced himself it never happened, for me though, I need a lot of support as I feel stuck and frustrated.
I'm now using SI to help me work on my M. How to better communicate and relate. It sometimes get's intense at which point I just log off until a topic I can relate to comes up, where I can contribute and support.
Take a break, but hope to see you back at some point.
