full of rage and need to get laid

Left my husband over xmas. He still hasn't moved out because he's not making enough freelance money working from home. Our only communication is texts about our kid. Last month I met someone. We snuck away to London on two weekends ('visiting friends'), and I 'worked from home' from his place a few times and the husband didn't know since I was still going to the office every day. One Friday I was at his flat when Boris decided the UK had to shut all its bars and restaurants. There goes my 'out drinking with colleagues' excuse for coming home late, I thought. Then the following Monday Boris announced the lockdown and now I'm trapped at home with a husband I don't speak to and a very bored child. I'm full of rage that I can't go get laid, and emotionally hysterical over whether this new 'relationship' will even make it through this.
