AITA for absolutely refusing to pay my ex girlfriend and her child after I came into money?

When betrayal and heartbreak collide with financial success, emotions can get messy—fast. After seven years together, I thought I knew my ex inside and out. But when she cheated on me and led me to believe her child was mine, my world completely fell apart. Now, years later, she’s struggling, I’ve come into money, and suddenly everyone—including my own parents—is pressuring me to “do the right thing.” But what happens when the so-called right thing feels more like rewarding betrayal?

Time to see how Reddit weighs in on this drama.

At the end of the day, I can’t ignore the fact that she lied, cheated, and left me shattered at a time when I was ready to build a life with her. Her struggles are unfortunate, but they aren’t my responsibility—nor is the child she had with someone else. My family may see me as heartless, and my friends may think I’m cold, but protecting myself from being used again isn’t cruelty—it’s survival.
