Marriage

Out of all of my friends, I've been with my guy the longest yet they've all gone off and gotten married after about 4/5/6 years. After 9 yrs of being with him I'm questioning if he even wants to marry me or is he content with life as it is. I'm 32, I want to start a family and I refuse to do so without being married. Call me old fashioned but those are my feelings about the situation. He already has a child. We've talked and he says to me that he wants marriage and a family and wants to spend his life with me, but I'm beginning to wonder if they are just words. I'm trying to be patient, but watching all my friends settle down, enjoy the happiness of security and having the men in their life make that claim and vow in love has me questioning my own relationship. I feel insecure wondering if marriage will happen for me, wondering if it will be too late to become a mother to my own, wondering should I move on, does he even take me seriously since he hasn't popped the question yet. I just feel so confused especially when people ask things like "you two aren't married yet?" "What you waiting for?" And so many other questions. I love my man. I really do , and he knows that I don't even want a big fancy wedding. Wouldn't even mind if we didn't have a wedding. Don't even give a damn about a ring. We've talked about matching ring tattoos. As long as we are together. So I just don't get it. I feel unworthy and it's making me question my value in this relationship and making me question staying in this. Am I wrong ?
