Emotional cheating is still cheating. You have to figure out what you want.
I suffered through it but it was an actual cheating. In the end you have to decide whether you'll trust him again or not.
Personally, I despise betrayal with a passion, so I am a bit biased; though I still want u to think if this fella is trustworthy enough after seeing a possibility that he would cheat.
"A cracked plate can break easily" After seeing that, his loyalty has become cracked imo. Yet in ur eyes, if u know that he is a really loyal fella and he loves u very much, then maybe this is really just a "joke" or something "to kill time" :/
In the end, it's ur decision
would u forgive a man of you where together for 5 years and he just so happens to have a meaningless relationship with some random woman on the I internet for like a day or two?? most technically they did not sleep together but they talked about it like it would actually happen one day??
