Cheated on while pregnant

So I just found out that I’ve been getting cheated on after 8 years together. To make things worse I’m 33 weeks pregnant. I have decided that I would rather deliver my baby alone than have someone I can not trust by my side during one of the happiest days of my life. It’s a heartbreaking decision especially since it’ll probably be a c-section and I’ll probably have preeclampsia so I won’t be able to do much for myself but I guess at this point it’s something I have to do
