<human>: Condense the text into a few key points

I am a 26 year old female and my SO is a 27 year old male. we have been together for 4 years and have lived together for 1 year. recently we had a long long conversation about marriage, a serious conversation. we have talked about it in the past but never in any real detail. the devastating conclusion was that I want to marry him and have for many years now. i don't **need** to get married now, but i know that i want to marry him. his response was that he is not ready to get married and dosen't know if he will ever be ready. he says he wants to try and wants time. but i keep thinking to myself  that after 4 years you should know if you want to marry your SO or not. i do believe he loves me very much and i am completely in love with him. so my question is, because i love him to i push the idea of marriage out of my head and just enjoy being together, or do i leave the relationship because if he doesn't want to marry me now he will never marry me. he is my best friend and my whole life and i have never been more conflicted. it's even more heartbreaking because we are not even fighting, we just both keep crying about not wanting to loose the other one. please help.  - 00clemmy
