<human>: Give me a shortened version of the text

My girlfriend ended things with me due to her losing her feelings and as amicable as possible almost two months ago and we haven't had much contact since.  

On the weekend I was out drinking with friends, and ended making out with a girl for most of the night. Sunday was spent nursing my hangover, but today I've woken up and I have a deep burning sensation of guilt?

My ex girlfriend still has a lot of her possessions at my (was our) house, so maybe it that's why. 

I'm not even sure why I feel guilty? Maybe It's because I still care about her, and it still feels 'wrong'? 

Reddit, slap some sense into me please.
