Excuse my venting 😭😭😭

I’ve never felt so alone in my relationship than I am now. Bf/so/ fiancé I don’t know what to label him as of now in all reality he hasn’t been acting like either since baby boy was born 11/30/18 well really since I was about 7months pregnant I’ve been feeling lonely af. We’ve survived a damn near death experience together last month but I still feel the distance. He’s proposed to me last month as well but not even a week later told me he basically doesn’t want to marry me anymore the ring doesn’t mean anything to him. I just feel like an emotional wreck and just want my love matched because I love this man with everything in me.
