Do two wrongs make right 🤔

[Strongecoffeeismydrug]

Long term partner had an affair with older lady 18 months ago,I found out and threw him out he moved in with her.4 months later I let him come back and although I believe he's been faithful since I don't have the same feelings for him and certainly can't forget the hurt I felt.
Now here's my dilemma I've always know I'm bi sexual and I've had plenty of offers from a lovely lady I work with but I've always just flirted because I think if your in a relationship you should stay faithful.
But now I'm almost obsessed with having a discreet fling with this lady just to spice things up and have fun.
I know it's wrong but would I forgive my long term
Partner more if Ido the same ?
The female and myself only want casual fun not a full on relationship 🤔

Grim.

If you want to fuck other people and your partner already has just end it and walk away.

Have you had an STD test?

1. Can’t blame you for thinking about it. Revenge and all that.
2. Makes no difference whether it’s a man or a woman in my view (or the age of your partner’s fling for that matter).
3. She’s at WORK. Big no no. Is she worth losing your job over?
4. Two wrongs will never make a right but you may feel you’ve evened out the score a little.
5. The main point... why are you with him? You obviously don’t care that much for him.

I've had a test I'm clear .
I don't want to end it I just want fun I suppose 🤔.
I wouldn't consider it if he hadn't cheated first.

Why don’t you want to end it?

He’s hurt you, you don’t and won’t ever trust him again, you don’t feel the same way about him you did before.

If you want fun then walk away and you can shag as many men and women as you like. You want to hurt him back, get one over on him, understandable maybe but it’s grubby and going to make you feel worse.

I don't want to
Leave him as we have a severely autistic child who adores family time with both of us,his world would be broken in two if I took his dad away for most of the week.
His dad still saw him daily when he was with his other woman.

You've admitted that you wouldn't consider an affair if he hadn't had one.
That's revenge, pure and simple.
Don't play games.
Either commit to him and don't have the affair, or separate.

His dad still saw him daily when he was with his other woman.

Then he can still see him daily when you’re with yours. Doesn’t mean he has to live with you.

Cheaters are a waste of space. Whining that he did it first if you get caught won't wash with anyone.

I'd do it then tell him and chuck him out.
