<human>: We've been dating for about 2 years and we're planning to move in together in about a year. We have a very good relationship, very open and honest and we love each other very much. We rarely fight, but we did last night when she asked me when I wanted to get engaged. I said when we were financially independent and stable. She said that she wanted to be engaged with the person she was going to live with and that just being her "boyfriend" wasn't enough. I told her that I wasn't ready and she's taking it pretty hard. Then she told me that she had been expecting a proposal and she never brought it up because she thought I was going to surprise her. We're both in a lot of mental pain right now. I'm trying to tell her that I will propose one day but I'm too young right now. She's too sad to consider that and won't talk to me right now. 

Am I doing the right thing? I really feel like I'm too young to be proposing, but I really do love her and can easily see myself marrying her someday.

Can you condense the text into three sentences or less?
<bot>: SO wants to get engaged, but I feel like I'm too young and not ready. Am I doing the right thing by making her wait?
