Worst friends ever
For us, there’s no coming back from infidelity. If a husband or wife cheats, there’s no more compromising, no more talking. Just serve them the papers and go. And if your spouse cheats on you with not one but two of your best friends, you might as well toss them in the garbage along with your spouse, too.
That’s what the poor OP went through before filing for divorce. The man whom she trusted with all her heart had slept with two of her dearest friends. This isn’t even a long triangle anymore. It’s a love trapezoid of sorts! Good riddance to that unfaithful jerk and to your two so-called friends.
