Hmm, good question. Whichever comes first in your opinion, according to the order of the poll options (or whatever you specify in the thread).Are you asking about physical or emotional cheating?
some behaviours whilst not exactly cheating are clearly unacceptable, I mean flirting occasionally with random women, probably not too bad, constantly flirting with the same woman every time you meet, uh oh.
I want to know if I should be pissed or not at my present partner.
This is our current argument.
Kissing is going too far.
Oh, My, another Minnesotan, You betcha.
If your partner would be signifigantly upset if (s)he knew it happened, it's cheating. It's different with every couple.
It's not about what specific action, it's about betrayal of trust and breaching what is expected. There are no rules that work for all relationships.
