He destroyed the relationship
Do you really beleive it is a completes strangers fault your partner was unfaithful with him?
He owes you more than she does?
Going after him gives you more facts. If the fecker was doing this knowing about you I'd hardly let him off without some heat.
If she slept around, sorry. Relationship is over. I need to trust the other person. Trust broken, its over. I couldnt keep it going with residual resentment. Better a clean break than it to limp on into the sunset.
I come from a broken home if this helps the pseudo-internet Psychologists.
As for the violence aspect, whose to say it would be violent? He'd feel stress/heat etc and only if he turned on me would I turn back?
In addition, Im not in that position nor have been (yet?)- whose to say I wouldnt actually crumble and do something drastic to myself? Hypothesizing is great when its not yet reality.
Funnily, someone on my street was telling me there is a bloke who lives overseas who darent comeback to the UK as he had an affair with a neighbours wife and the threat to his wellbeing is real. I asked why doesnt he just live down south etc- apparently the lad has asked him to leave (and stay) in a certain country?!!! Crackers.
