It's Complicated Now

So yeah, after seven years of marriage, we called it quits a few months back. Still living under the same roof, but with some boundaries in place. Last night, I couldn't resist and ended up sneaking into his bed for a quickie. Surprisingly, he was game too, even though we're technically separated. Feels complicated yet exciting, like walking on thin ice while having wild sex. Anyone else ever do something similar? How did you handle it?
