HELP! Overthinking again

The thing is, my bf and i were making out and it was pretty great, but i just didn't feel up to anything more. And here he was, all hot and stuff and i wasn't feeling it. So we stopped and he was super chill about it, but i feel like i wronged him somehow. I know it's not right but i can't help thinking, that maybe i should've kept going and i was still horny, so it would've worked, so maybe i should've let him, but i just didn't feel like i wanted and that's not that bad, i would've still felt good in the end. And now i'm in this limbo, where one part of me tells me that i don't owe him anything and another one, that says i should've done it for him.
