They are both my friends. They've been married for awhile. The thing is, this girl is a good friend of mine and we've been friends for damn near 20 years and they also have kids together. I'm on a business trip abroad and this guy came a day later. We were out and about and he was hitting on the girls here. He ended up taking one of them to his hotel and believe me, I tried my best to stop him, short of knocking his ass out.
I'm friends with him, but I'm much closer to his wife. He put me in a tough spot here since we hang out regularly. I won't be able to look at him the same way and the wife would be able to tell. I won't tell the wife, but damn this guy is a piece of shit. I'm genuinely pissed because I care about her.
