Should I let my narcissist ex bf / bd be in the labor room ?

Hello ,

I’m having a hard time deciding if I want my baby daddy to be in the delivery room w me to watch my son be born . I’m leaning towards no because he had left me whole pregnancy, haven’t been supportive , on top of raising hell all my trimesters , even went n got a gf & now she’s pregnant too , he stuck w her during her pregnancy. He’s very narcissistic, everything is my fault he DONT take accountability of his actions . He says he still loves tf outta me even held me n tried kissing me , but I won’t allow myself to slip back into that path even if I do love him & wanted us to be a family . Some stuff he just took too far . I wanted him to be here to watch my son be born but why let him be there when he’s dogged me my whole pregnancy n left me to do it alone ? Why spare him when he didn’t spare me & left me high & dry . Even let his family n gf talk about my child & never addressed them & told them

Where I laid my head at , where I worked at & even laughed when they tried fighting me thru more then half of my pregnancy . Now he wants to be here & wants to see him be born . Yes , I want to be the bigger person but why spare somebody who hasn’t been here for me n caused so much pain during my pregnancy, shouldn’t I bring my child into a welcome environment? What should I do ?
