<human>: Can you condense the text into a few key points?

Kinda new here but here goes. I (m/20) have been dating this wonderful woman (f/23) for 7 months and everything has been going well save for this feeling of inadequacy I can't shake about our age difference. The small things add up and eat at me. How I can't hep her with her taxes. How she has to deal with shitty roomates in her appartment while I live comfortably at my parents home. She worries about scraping up enough cash to pay for her insurance (her family is pretty impoverished) while I dont have to worry about any of that (my family is pretty well off). There;s also the issue of me being just a immature goofball in comparison to her. She has all her stuff in order from her fafsa to her w-4's while I'm kinda just laid back, even though I try I just can't keep up. I feel like a kid around her sometimes. We have sooo much in common, but I still feel like we are just too different.

All my friends poke fun at me because my GF is more mature and knowledgable than I am. Normally this doesn't bother me, she's a lovely and considerable person and I always love learning new things. It's just I never see guys with SO's that are older with them so I can only assume it's because those relationships tend to not work out, right? The guy has to be the mature "man" for there to be balance right?

 I don't know.. I really just want what's best for her and on the outside I want to just stay with her, but deep inside I know I wouldn't be able to provide what an older more mature guy might offer. I've been having thoughts of breaking it off. I know it'll hurt her quite a bit at first, but I think she'll be better off for it. At least, thats what Im thinking.. What should I do reddit?
<bot>: GF is older/more mature/more knowledgable than I, should I break up so she can be with an older guy?
