Help,should i keep the relation to this girl?

so it was last night when i met this girl on the club. my friend invited me to the club to have drinks and i met his friends then this girl i used to make yes on the relation was in the same table, during the drinking session everyone is knowing and finding a partner but this girl and his boyfriend are having an issue because she and my friend are having intimate talk, it didnt take long and her boyfriend ended their relationship after the party, i accompanied the girl in waiting for a ride to go home, i hold her hands and she said this relationship is only tonight and will be forgotten and i asked her what if we keep on this relation and she said yes, we kissed and im influenced by alcohol and after a hour the alcohol influence is loosing and i lost my feelings to her and i said to myself i dont like her physically.
