<human>: Condense the text into a few key points

This happened a few months back and recently came into fruition.
A month after I broke up with my ex-girlfriend, I ended up sleeping with a girl I had a crush on, knowing that she had a boyfriend. First, we would just hang out together with friends and get drunk then make out. After a few weeks of that, I ended up sleeping with her. 

At first guilt was a huge factor so I decided to end it there, and rejected her advances for the next month or so. The fact that she still was with her boyfriend did help. However, one can only resist temptation so many times and I eventually ended up sleeping with her again. 

Fast forward, she has now officially broken up with her boyfriend and I do have the intention of chasing after her. However, I am worried as our relationship started off wrong and I'll always wonder if she'll do the same with me.
<bot>: Home-wrecked. Ended up liking the girl. Worried how to go about chasing after her or if I should at all.
