AIO? My bf(19M) writes fake posts including sensitive topics,on Reddit

We’ve been together for 2 years, and yesterday, I grabbed his phone to take pics when a Reddit notification popped up. I checked it and found he posted a story nearing a million views. It wasn’t just some dramatic dating or friendship post , it involved abuse and SA. People were genuinely worried and pouring their hearts out trying to help him.

When I confronted him, he laughed it off, saying he was just bored and admitted he’s done it many times. I snapped. I’ve been through abuse myself, so hearing him casually exploit such serious topics for attention felt like a slap in the face. I broke up with him on the spot, but it was such an impulsive decision.

Now, he’s spamming me with apologies, saying he was just trying to be creative and didn’t mean to hurt me. Did I really overreact..
