<human>: Can you summarize the given text in a few sentences?

So I've been seeing this girl for a few months. We've both said how we're falling in love with each other several times. Tonight i planned on telling her I love her. She's beyond beautiful , we share all the same interests and shes the most positive and nicest person I've ever met. Last night we hung out and talked til like 3am and went to bed. We had to wake up at 7am since she had to work.

We made plans for a fancy date later in the night. I was ready to pick her up at 8:30. Got all ready, ironed my clothes got dressed and actually combed my hair! I sent flowers to her office during the day and bought more for the night so it would be extra special. I finished getting ready early and laid down for a minute, giddy with excitement. I ended up falling asleep. i slept through my alarm and her phone call and missed the date. I texted/called her and told her it was an honest mistake and said I promise to make it up to her.

I asked if she wanted me to come over and hang out tonight and tomorrow. She seemed pretty upset (understandably) and said she needed time to reflect. I don't know if she believes I honestly fell asleep. I don't know what to do. I'm head over heels for this girl and don't want to lose her. any advice is greatly appreciated.
