<human>: Can you succinctly summarize the text in 1-3 sentences?

A few months ago I proposed to my girlfriend of just over a year. She was totally caught off-guard by my proposal, but said yes. Now she feels obligated & helpless.

I knew it was early for a proposal, but I justified it with the whole: "When you know, you know" mantra. I also assumed that she felt the same & had given it as much thought as I had. I thought the proposal was better off unexpected so I didn't drop hints.. wrong, I should have come out & told her how I was feeling. We had talked about our futures, our plans, how many kids we want & how we'd be spending our lives together, now I see she was wistfully thinking about our future while I was planning our life & thinking marriage.

She swears she loves me & wants to marry me, but she wishes we could reset & have a storybook love with a proposal she was prepared for. She hears stories about guys dragging their feet & wishes she had been ready before I was. She also mentioned that the pressure from the proposal makes it hard for her to feel like this is a mutual thing. :( Meanwhile I am scared that she will always resent my improper proposal, I'm willing to put off the wedding or do anything to fix this, but I'm afraid the damage is done. We moved in together & have been moving forward with the wedding planned for late 2015 until last night when we discussed her feelings about this. Now I'm not sure how to proceed.

Background: We're both professionals relatively established in our careers, established lives & lengthy relationship histories, our lives are good. We are compatible in every way we can think of, no big conflicts - except I'm quick to make big decisions & she needs time. I can give her time, but I need to do it right.

Has anyone ever been here? Any advice or stories would be greatly appreciated.
