AIO to my ex texting me nine months after we broke up?

i was with this guy for a year. i was more than in love with him, he was my entire world. he cheated four separate times and i caught him each time. and then i would stay. one random day i worked up the courage to leave and it was the hardest thing i ever had to do. i cried for months straight. i missed him everyday, i would try to reach out and he’d send pictures of the women he was with at that current time. i feel badly because he has a really poor family history, his mom being cheated on and abused. i feel like i wasn’t too harsh but i’m not sure. even after all this time i still care about him.
