MY EX does this mean soemthjngg

so there was this party where my ex was also there like we're friends ish but anyways i had to leave early because i had work the next morning and when i left people got pretty drunk anyways my ex had sex with this chick that im aquaintance with its not that i want him back but im so dissappointed i guess. One of his friends told me they had sex while he was at the oarty anyways and i found out and his friend was talking about it today when we all ran into each other his friend is also my friend and all i said was ew lol ik immature. Then he texts me today asking if i was mad? I told him i wasn't mad i was just disappointed and he said same. Does this mean something?
