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

Hi all, I need help :)

I Met my girlfriend 18 months ago, at first I thought she was just a rebound after breaking up with my first ever love of 5 years, but I accidentally fell in love, real love.

We got together and for the first 6 months we were extremely happy, weekends away, dates every week, just a perfect couple.

Then a few arguments started, and we both became sort of lazy in the relationship, we'd still be happy when together but we wouldnt do anything but watch films, eat, and have sex.

Fast forward to two weeks ago, we had a huge argument and decided this was the last time, we're done. I said some things, she said some things, we hated each other. I've felt & been sick since the breakup, and im very stressed.

We both rebounded during the two weeks it turns out, she had 2 minute sex with a guy at a party, and I had a girl over to my house, we've laid all the cards on the table and agreed to a clean slate, we are texting as if we are a couple again and we plan to start dating / spending time together in the next couple of weeks.

So why do I still feel sick? All I wanted was her back, and I have it, But I still feel awful! I'd love to hear your thoughts. thanks :)
