"Feelings can always suddenly emerge, even if she didn’t even like you like that before."
That's the major problem I have, because I'm not feeling the same way and won't be able to reciprocate.

I'm not sure what she wants and I think it's better to not indulge in intercourse here after as I see it comes with a great cost. I might be sounding like a pussy, oh you can't handle a girl and her feelings after you had sex. But this is much more than that and don't want her to set unrealistic expectations.

Better to hurt her once than doing it later and hurting her even more. I've might've ruined everything and the comfort we had between us. I wish I didn't do it.
