<human>: Okay, so I know we're young, and we were each other's first almost everything. We had some problems in the past with him not trying in the relationship (the worst was he went to a party half an hour away and made me drop him off and wait around in my car by myself until he was ready to be picked up) but he has since matured, and has proven to me that he's matured (he did that in years 1-3, but 4 and 5 he has been much better). However, we have been long distance during the last 2 years, seeing each other a couple of times a month, and over school breaks. so my initial query is do people really change, or when I move back once I graduate in a couple of months do you think it will go back to being like that? (it's hard to judge because we've been together for so long and he was my first, I'm just looking for a wee bit of perspective). He's a great guy, attractive, ambitious, and we have similar life values and humor, plus our sex life is fantastic. He's super giving and kind. 

I guess the biggest issue is that I bring to r/relationships is every time I try to talk about our future he clams up and doesn't want to mention it. He constantly is talking about his future career and life, but he'll always say, "one day, my wife and I will..." But at the same time he'll sometimes-- sometimes say, "I want to spend my life with you/ you're everything I want in a woman, etc." But it's nearly impossible to get him to actually open up and talk about our future. It's just frustrating, and I'm wondering if this is normal (I know it takes guys longer to commit and take the next step, but 5 years and still unable to open up?)

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Do people really change, and is it normal that my 23 yr old SO is unable to talk about our future together?
