Am I going crazy?

So I have a friend who my wife and I hang out with. Don't want to go into too much detail but he's my wife's friend as well and we are all familiar with each other.<br><br>So lately I've noticed he has definitely changed. We always used to share laughs together and stuff but now it's a tension. Specifically he and I.<br><br>We haven't had a good conversation in months. I'm starting to feel like maybe he's angry with me or something. I don't even know man. It's kinda crazy. All of a sudden he's mad. I think it's more than that. All of us have known each other for a decade.<br><br>Am I going crazy? Maybe I'm just being paranoid. But it feels like he's definitely mad at me.<br><br>Is there a way to know if someone is angry with you?
