Was i wrong?? This is risking me my fiancé

Adrianna

So i posted a meme that i though was funny and a friend from high school commented on it. He know I’m engaged. I am almost 11 weeks pregnant, and my fiancé started commenting back.. and took it waaay out of context. And i told him it was nothing. I would never do that i am engaged and pregnant by him and I’m happy and all he said was “fuck off” and “i want my ring back”.. what do i do. I mean if he is shaky right now then what makes me think he wont just dip out after the baby is born? Was i in the wrong wht should i tell him?
