Stress

My fiancé stresses me out beyond words and I’ve been trying super hard lately to stay stress free since I’m pregnant but he nags it on. He’s never around, he’s not here emotionally or physically for me, he thinks I talk another guy just because he doesn’t have my password and not to mention I walk out to him masterbating to porn 24/7 and it’s just so inconsiderate and he never stops. I don’t know what to do... I didn’t expect to be pregnant by someone like this.😪
