Early marrige

I have a friend，she got married when she was 18 because she was pregnant.Her baby was born in the next the the following year. She and I were in the same primary school. I still remember that I got along with her very well at the time. But now，there are too many differences between us. She is the mother of a three-year old child and has a family while I still live on campus. Personlly speaking，I don't support early marrige <em>and even oppose it strongly(this is not gramatically incorrect, but sounds kind of strange)</em>！For a teenage girl，she doesn't even know herself very well，let alone another person. Also，she is She is also immature both physically and psychologically. There are many things that she never tries has never tried and she may never have a chance to try once she gets married. Early marrige often means a kind of <em>tie(It is unclear what tie means in this sentence.)</em> and high divorce rate. Because she has to sacrifice her youth to raise her children and take care of her family. How can she do these things well when she still needs to be taken care of？
