Marriage and Babies

At my age, as I look around it feels like everyone is getting married or having a baby. Now I know that not EVERYONE is. In fact I have several close friends who are doing neither at the moment but when I look around I tend to notice all of the people who are. I am only 21 years old, but I have this humungously strong drive to be a mother. I am in a relationship that I have been in for 3 1/2 years now and I am very happy. I would love to marry the man I am with. He however is not ready. He wants us to have a decent savings before he proposes. I completely understand this, however I want to get married now. I want to have a baby now. I know its not logical. I do want to be married first...so I want to get married now so I can be on my way to having a baby. I really want to be a mom. Ever since I was a child that is all I've felt a calling to. I am meant to be a mom. Whatever else is meant for me to do I do not know right now, all I know is that I want to be a mother and a wife and I cannot knock this urge. So right now I'm just floating through life waiting until the day I can have my dreams come true. But then I think to myself "what if I die tomorrow"? Life is short and you never know when it's going to be taken away from you. So if I died tomorrow I would have an unfufilled life because I would never have gotten to be a mother and a wife. So everynow and then I convince myself that I shouldn't wait, that I should just go for it. But I don't. Because it takes two to tango. I don't push the topic on my bf too much because I know that if I brought a child into this world right now I would not be able to provide for it the way that I want to. Anyway, my point is that I am sick of waiting I want to be able to just do it. Do what I want and have what I want now! I do not want to wait anylonger. But I will. And it will be so much better when I finally get my wish because I will have waited long and hard for it to come true.
