She's older than me...some times i feel thats the problem?

she's older than I am....and more educated. I dated her with the intent of embracing how different we are, yet so much alike. We're alike as far as what we want out of life and how we view our relationship. She's a divorcee. I've never been married. Niether of us have children of our own. She is at a point where she really really wants kids (33yo). I'm at a point where I'm ready to meet my future wife, I also want children, but not as soon as she do (26y/o). She has advanced college degrees (masters and working on Phd). I am a college drop out but work two jobs and am just as ambitious. She admires my drive and my ambition. I admire the same of her. The beginning of the relationship has been a little rocky b/c communication sucked, mainly b/c she and I are terribly busy, her school and working full time....and my doing 70+ hours a week btween both jobs. we've tried working on how well we communicate and i try to present an open and honest enviroment for us to communicate. She's more reserved in nature where as I'm very extrovertive.....anyway, the constant back and forth between her and I about how I'm "seeming" too aggressive or assertive in my approach (when i was simply trying to be romantic) and her drilling me with "slowing down" and so forth has honestly caused me to be more reluctant in my approach. Seriously we hardly see eachother and i really have tried to express how I'm romantically interested in her....but some how she always read into my actions and approach differently? anyway we agreed to slow things down (as if things arent slow enough) and to not jump to sex.....but the two times that we got intimate it was her that persisted or initiated in a sense.....and well it has confused me. I mean the first time we shared an intimate moment she felt guilty afterwards (bc she felt she was crossing the line)and just made me feel bad for ever even taking her clothes off....even though we did nothing, mainly b/c I couldnt perform b/c i sensed uneasiness from her. but i was willing to take things slow with her. i'm in no rush to have sex.....a month and couple weeks later (last night) we again share an intimate moment, and yet again I was reluctant (just a week ago she scolled me at how she feels rushed and pressured by me and so on) but she was persistant. i couldn't say no, b/c I really wanted too....but i guess my body was saying wait...and I went soft....she's upset. I know. she wouldnt even kiss me last night just turned to give me her cheek. i tried talking to her in text today and was trying to plan that we relax in a jacuzzi tonite... i told her how i'm so unsure with her and this adds to my anxiety...I clarified that i am very interested in her and I really do want her....but anyway she told me how i need to slow down and etc, then she mentions that we have "time". ??? but anyway I'm reflecting on the relationship in general, and though I am attracted to her.... I'm just wondering, is ther anything that could come of her and I? I feel that she and I share similarities as far as our morals and the way we think....but at the same time we are sooooo different. and I mean i like different b/c it spices things up...but she and I are almost TOO different. you know? I do appreciate all who reads this. Though I am not interested in shallow answers, I am looking for more indepth answers. Real answers, if you will.
