Fiancé is doubting me (pics)

Last night while my fiancé was at work he texted me saying that there needs to be a conversation before we get married...okay? Sure. Before he sent that, I sent him a semi-sexy Snap (mostly to show how bad I got sunburned after my run earlier that day) but I also wanted to be spontaneous because I don’t sext/send sexy pics anymore since we live together.

He goes on a tangent telling me that he doesn’t trust my friend (for sake of the post) Robert. Backstory of me and Robert: no we haven’t done anything together, we worked together for 3 years and I was good friends with both him his wife (she worked with us too) and they ended up getting divorced only 2 months ago. He’s been there for me as I have him, and we’ve been friends far before I met my fiancé.

HE THOUGHT I WAS TRYING TO SEND THE SNAP TO ROBERT AND BLEW UP ON ME.

I told him that he was crazy and that Robert knows EVERYTHING about us minus any relationship drama we have. Why would I cheat? I have nothing to hide especially since I moved for my fiancé. I told him if he can’t trust me, then we shouldn’t get married and I hung up.

This text conversation was right after we got off the phone the first time.

He calls me again after that long text I sent and told me that he still doesn’t trust me and that his insecurities don’t derive from his ex-fiancé cheating on him (which I mentioned during the first phone call) but because I’m not as sexually spontaneous as I used to be?????????? That day I was trying to spice things up for him and we had sex twice before he left for work, but somehow the pic is weird??? So he thinks that the snap was completely out of the blue and that he hasn’t seen that side of me in months and that gave him all the reason to feel insecure.

Mind you he DOES have female friends that he texts and snaps but I have never blown up on him the way he did, one of them being a girl he has actually slept with but she lives states away and I trust he isn’t doing anything.

He texted me at 6 am while I was asleep—he at work—that he was going to kick my ass. He didn’t, but I’ve never heard him so verbally angry.
