My husband doesn't love me

I don't feel loved by my husband. Nothing is gonna change him...he's just gonna continue to be an asshole....I'm gonna have to take my baby and leave child can't grow up like I did. I want he/she to be happy...I don't want them to know violence and abusive words or that their mother is in a bad space. I don't want them to see my tears. Everyday won't be  roses and sunshine but I want them to be able to see Their parents can argue and be ok and still act out of love and I'll never get that. My biggest fear is that the stress from my horrible marriage will. Cause me to lose this beautiful creature growing inside of me. Positive vibes, prayers, and advice welcome
