Thanks for your insights! They are highly appreciated. It’s indeed a lot of grey zone. First, I told him I want a divorce. He asked me to wait. And coparent together. We slightly touched upon about seeing other people and while we joke about this, he doesn't seem into opening the relationship claiming he doesn't need other partners. We know that we will eventually get there but for now infidelity looks better than divorce for all of us. I am responsible in all ways and not exposing him to any harm (I am discreet and hygienic). Our relationship has improved and our sex life too. My therapist says it's not unheard of. So for now, when I draw the line, there are net benefits. Will it still be the same in a year from now? I don't know. Only time will tell.
