In love with a cheating man.

I am broken, I am truly disappointed in myself. I can't believe that even when he has caused so much pain in my ♥️, I still love the father of my child but I want him out of our lives. I don't know what it is, why he doesn't just leave.. Why he did this to us while we were expecting out first born. Why would he do this when i have broken my back for him so many times. I will never have any answers to why he would risk losing his son for some dumb twat who not only knows he's married with a baby on the way but even stalks and rubs it in my face that he's seeing her. I am utterly devastated, extremely heartbroken and frustrated with only a few days away from going into labor... I don't know what to do sometimes i wish i was dead because of him but i know my baby needs me. Will I even be good enough? I hate myself and i hate them and i am going crazy thinking about all this. Please just end it now. Please. I dont want this pain anymore
