<human>: So i'll try keep it brief although i think some details are important.

Basically, i hooked up with a girl i work with a couple of nights ago after going out after work and getting drunk. Everyone else had gone home and in my drunken state it hit out with the 'so do you fancy going out for a drink sometime like just us' line (even though that was the exact situation we were in derrrp)

So basically, one thing led to another and i ended up staying the night at hers. Thing is (heres the problem) I've just finished up in a 4 year relationship with my ex a month or two ago and i've been devastated by it. It was a total surprise when she told me she didnt want to keep going.

I've managed to keep on the rails by and large and not just go out and get smashed, get horny and get into trouble. Well, last night the train wobbled. Fact of the matter is, i like the girl as a person and have a lot of respect for her plus i think shes pretty attractive, but i've been plagued with feelings of guilt, shame and regret since it happened and all the raw feelings towards my ex have resurfaced.

To make it as simple as possible, i got drunk and fired into a girl i work with and asked her out. Now i think that was a bad idea and i'm looking for ways to say that without being an asshole. Despite my poor decision making so far, some of the guy responses i've heard so far would undoubtedly turn this hole into the grand canyon so i'm particularly interested in hearing the female side of things.

That said, i do genuinely have alot of respect for this girl and it would bother me if she thinks im a terrible person. Any advice on how to make this not be the case would be appreciated.

Can you give me the gist of the text in a nutshell?
<bot>: hooked up with a girl from work, brought back flooding memories of my ex, now i feel weird and freaked out want to stop anything before it starts in the least assholish way possible.
