together for almost 11 years, 2 angels in heaven and a daughter...still no ring?

my SO and I have been together since I was 15 and he was 17. we have had our ups and downs and broken up over the years but never stopped seeing each other. in 2014 I moved to another state to be with him and became pregnant in 2015 but unfortunately lost the baby at 6 weeks due to PCOS complications. we made it through and I became pregnant again in 2016 and welcomed a baby girl in may of 2017. but even after all lthis time and everything we have been through he still doesn't know if hesbready to marry me and I'm just curious if anyone else has gone through something like this and if you have any advice. I know its how he feels I just wish he understood that it hurts knowing he doesn't know I'd he wants me the rest of his life after almost 11 years, 2 angels in heaven and a beautiful daughter. TIAL
