am i not good enough for him

i broke up with my ex because i am done tolerating his bs. i’m malay and he’s chinese, which was hard on his family as it is already. we dated for about 8 years. we did ldr for about 4 years due to uni and towards the end, he left me for someone from his uni. apparently after graduating they’ve been secretly meeting up for “work trips” and pretty much slept together on those trips.

i did so much for him, is this karma for dating out of my religion?
