Outlier opinion on the topic...
For me Love =/= Sex. But carries with it the contradiction that I'm in no way for Open Relationships. Call it a sick and twisted mental game if you wish, because it pretty much is.... but like I said, very much an outlier opinion. So here goes...
Cheating to me means...
1. -- That you're in an accepted to be exclusive relationship
2. -- You're having sexual fun outside of said relationship
3. --
a. -- Falling for said other person beyond your partner, and or the outside fun is drawing you away from your relationship partner
b. -- You and the person you're fooling around with are incapable of keeping your mouths shut about your actions and or keep it 100% secret and seperated from effecting your normal lives in all forms imaginable. (Getting caught in any way shape or form factor / things changing inside your current relationship to accommodate your outside fun)
So... with my version of what I'd call Cheating, the sex isn't the primary issue. The main issue in my mind comes when the person doing the sexual stuff beyond their relationship does it, and then loses even 1% of feelings for their current partner, or want to leave their partner for said other person they're fooling around with. And.... they can't keep their actions away and 100% hidden and able to do it and have it NOT effect their current relationship in anyway shape or form. No love lost, no changing of schedules, etc etc.... if you can't do the deed and prevent those factors... cheating.
If it's hidden for all time like it never even happened, doesn't effect the relationship you're in or cause the feelings of said relationship to change at all... not Cheating to me because it's 100% as if it never even happened.
If my lady had done this behind my back I'd never wanna know, never. So long as no STD's are brought to me or my family, she loved me still 100% and i could tell nothing changed... and nothing changed at all 100% about our lives and it was totally hidden. I'd never wanna know. Because yes I'd be hurt to find out. Hence why I prefaced it with "it's a contradiction and definitely a sick and twisted take on it".
The other side of the coin where I said sex doesn't equal love. It just doesn't to me even if I would be hurt to find out the woman was banging some dude behind my back. It more means that I could literally live a sexless relationship so long as all the other factors of love were there. The cute stuff, the kissy kissy stuff, cuddling, can't live without that person factors. Those are all totally separate to me away from sex which I only see as for fun / pleasure / kid making. Sex or the amount of sex I'm having or not having means nothing about how much I do or do not love my partner once the feeling of "true love" has been established and is in place.
Why would people even want to cheat and stay?
For me it's what I described above... being "put into action". I wouldn't be fucking the other girls because I loved them, or wanted to leave my partner for them. I'd just be banging them because they're hott, trustworthy girls, or good friends that I find to be sexy and wanna fuck. On the occasions that I have banged outside of relationships I've been in, it was never coming with any emotions or feelings attached to it beyond the ultimate form of friendship. And in no way made me ever WANT to leave my current partner even if the sex became a more than once "itch scratch / why the hell not, so it once and get it over with" thing.
If I ever started to lose feelings for my current partner because of my outside fun, then it was going too far and it had to end... (Never happened for me, so that was never an issue, and never got caught *shrugs* call me lucky or call me just being smart about it)
Still loved the girl as much as I ever did before and after, or after the 5th time haha. Why would I ever give up an amazing and love-filled relationship for some pussy.
But yep.... that's my version of "Why would I stay if I'm going to or already am fucking other people"
Because love and sex aren't hand in hand to me, even if I am against open relationships and don't condone them.
I know my thoughts on it are sick and twisted to the conventional ideology of "relationship".... but that's how it is and my "how I could".
Take it for what you will.
