Mourning a loss .. or not?

Okay so my fiancé and I are ttc. On the day we were supposed to have sex (the day we got a positive ovulation test), he got a call saying his cousin was killed.

He then obviously cancelled the baby making plans because he didn’t feel like having sex. I understood. And then he told me he wanted to go out and party with his friends, drink and smoke weed. Apparently that was his way of “mourning” his loss. He’s 24 btw so maybe that has something to do with his choice of mourning.

BUT, he posted pictures on social media of that night. Pictures with his friends like some photoshoot. His friend also recorded him passed out in his car after drinking too much and my fiancé screen recorded the video and posted it as well.

Now maybe I’m just being insensitive but how is that mourning? I’m having a hard time believing that he was actually hurt. Part of me feels like he just wanted to blow off our plans (like he has before) and do his own thing. Am I wrong? I obviously haven’t said anything to him about it because I just don’t know what to say. Should I leave it alone?

- “it’s not your place to tell someone how to act”... was I telling him how to act? I didn’t even mention anything to him. God I hate you condescending bitches on here

- I got told the truth? Where was that at? I wasn’t even calling you a bitch but now I am 😂 Eat a dick and get off my post H

- I didn’t want anyone to be on my “side”. There are no sides here. I made this post to see if I was just being insensitive to the issue or maybe I was actually on to something. Like I said, I wasn’t telling him how to act. I never even mentioned anything to him sooo yes, refer to my last edit, thank you!

- Now Im insensitive huh? But you didn’t say that from the beginning did you? Oh ok. I don’t know why you’re still here H
