I accidentally cheated on my girlfriend, what should I do?

So my girlfriend and I got in a fight as I don’t like her ‘friend’ that is a male. They always spend time together and it makes me feel jealous. I left our house as I wanted some fresh air and drove to our local city for some drinks.

I wasn’t thinking and ended up hooking up with a woman that I met there.

My girlfriend found out when she saw our joint credit card statement, it had the hotel booking on there. I haven’t admitted I cheated but I came back home on that day after hooking up with the girl so she can put it together and guess what I did.

Anyway, what would you guys do in my situation? It was a total accident.

Not sure why everyone is saying it wasn’t an accident when it clearly was, I didn’t mean to have sex with the woman.

A lot of you are taking her side automatically and victim blaming me.
