Little more info. She finds out im texting other girls. I loose frame start talking about how im sorry how it means nothing i hope she will forgive me. Cringe....

She leaves and 5 minutes later calls me to meet her outside that she wants to talk.

This is the point i regain my frame after realizing i lost it earlier. I tell her that i understand her anger, but i wont ask for her forgiveness and that it was really fun to be around her. (it really is, even tho i think we are slowly turning in to a toxic relationship, if that happens im definitely jumping off).

She then tells me how she doesn't want to break up and is scared to look like a fool for "forgiving" me and how she only wants me to promise her that i tell her if i ever find another girl and not lead her on. I say i promise. We kiss goodbye.

Now im here wondering whats the best way to proceed after this. Should i act like nothing happened or should i maybe insert more comfort. I was never in a situation like this before.

P. S. I know i didn't play this the best way. And that i lost frame. I guess i have a lot to work on still. And before anyone asks. We are in a relationship because i really have no time to spin more girls. Maybe 2 max. That's the main reason i entered the relationship. And she has a high interest in me. Which is probably why she changed her mind so quick, meanwhile even tho i like her i can't say im really into her, after TRP i hardly have big crush on girls but i guess that's a good thing.

Anyway im left in an uncomfortable position now. I don't know whats the best way to approach this. Or should i step off. Im 22 she is 20 btw.

EDIT: what's the best way to react in a situation like this?
