I sent my boyfriend an itemized invoice for $14,280 in babysitting services and he called me a "vindictive bitch" in front of his kids.

His ex-wife just texted me saying "thank god you finally left him."

My boyfriend has two kids, 7 and 9. We've been dating for eleven months. I don't have kids. About four months in, he asked if I could watch them "real quick" while he ran to the store. That turned into every weekend. Then weeknights. Then overnights when he had work trips. I never said yes to a full-time unpaid nanny job, but somehow that's what I became.

Last week I overheard him on speakerphone with his friends. I was in his kitchen making the kids lunch. He was in the living room laughing about something and I heard my name.

His friend said, "Bro, you're lucky. Free childcare."

My boyfriend laughed. "Yeah, she's a single woman dating a dad. She knew what she was getting into. She owes me for even giving her a chance. Most guys don't date women without kids."

I froze. The butter knife was still in my hand. His daughter asked me if I was okay.

I said I was fine. I finished making sandwiches. I didn't say anything to him that day.

But I went home and I did the math. Every babysitting session since we started dating. I used the average rate for two kids in our area, $25 an hour. Weekends, overnights, after school pickups, homework help, baths, bedtime. Everything.

$14,280.

I made a spreadsheet. Dates, times, hours, rate, total. I added a line at the bottom that said "Amount Owed for Services Rendered." I exported it as a PDF.

Then I went into the group chat he'd been on speakerphone with. Six guys. I'd met most of them. I sent the invoice with a message: "Since I'm free childcare and apparently owe him for dating me, here's what he actually owes me. I'm also blocking him. He can Venmo me."

I blocked all of them. I blocked my boyfriend. I packed up the few things I had at his place while he was at work and left them on his porch.

He showed up at my apartment that night banging on the door. I didn't answer. He screamed through the door that I was insane, that I'd humiliated him, that his friends were clowning him, that I was a petty psycho who couldn't take a joke.

The next morning his ex-wife messaged me on Facebook. We'd met twice, very briefly during kid handoffs. She'd always been polite but distant.

Her message said: "I don't know what happened but he's losing his mind and I heard you left. Thank god. He did the same thing to me. Made me feel like I should be grateful he stayed after I had his kids. Like I owed him my entire life because he didn't leave. I'm sorry he wasted almost a year of yours. You deserve better."

I didn't respond but I didn't block her either.

My boyfriend's sister called me yesterday. She said I was cruel. That he's a single dad doing his best. That I broke his kids' hearts by leaving without saying goodbye. That the invoice was humiliating and immature. That I clearly never cared about him or his children.

I told her he literally said I owed him for dating me and that I was free labor. She said I took it out of context. That men say stupid things to their friends. That I should have talked to him instead of "airing everything out."

I hung up on her.

But now I keep thinking about his kids. I didn't say goodbye. I just left. They probably don't understand. And maybe the invoice was too far. Maybe I should have just broken up with him privately instead of sending it to his friends. Maybe I did humiliate him over something he said as a dumb joke.

His ex says I did the right thing but she also hates him, so I don't know if that counts.

AITAH?
