No ring

Ba
I really never thought that It would bother me that my SO doesn't want to get married . However now that we are having a baby I'm worried he will never marry me. Most of his friends are engaged and the girls are always showing off their rings and talking about how much they cost. Maybe I'm just being a big baby but it makes me jealous that they are engaged and we are not. I wouldn't care if he proposed to me with a cheap ring or no ring at all I just wish he would ask. I don't want to talk to him about it because I know he will get defensive about it and feel like I am pressuring him. It doesn't help that my mom keeps asking me when we will get married.
