I Lied To Get Him

When me and my husband were just dating we had an argument and split up no biggy it happens. I offered him more sex than ever to keep him coming back because I didn't want to loose him though but it wasn't enough and he felt smothered so I degraded myself to stop him going and failed and had to think of a plan.
I waited a few days and told him I was sorry but its OK I've moved on and have a girlfriend now who I'm happy with but I'd like to be his friend. He was happy with this and things were going great I even managed to convince him to stay a few nights here and there and he didn't suspect a thing I was back dating him and giving him sexual favours behind the back of an imaginary person until the day he asked me back and I text my other phone so he thought I'd dumped her.
I've not told him the truth in over 20 years and still lie saying I'm bi so he never questions it
