Input: Text: so this happened about a month ago, i was still with my crazy and manipulating ex girlfriend we will call her mia (that was her stripper name when i found out the truth) so we were moved out together and living happily together she was pregnant and i thought it was my kid.

about 2 days before the initial breakup i find papers of her date of conception and the numbers didn't add up she conceived a week before we actually became physically intimate again so the baby wasn't mine, here's where the initial fuck up begins. i'm a gamer, play counterstrike competitively so i devote quite a but if time to team practice, its the weekend we have matches scheduled so she tells me she's gonna go to her friends to spend the night. at the time she told me she worked graveyard at her grandparents company which i thought nothing of because it seemed legit. so she leaves and doesn't come back until 11 a.m so i start getting suspicious, i don't call her out on it because maybe i'm wrong and maybe its all just me being crazy but i was so wrong.

i come to find out as sunday rolls around that she left on my car in the morning and came back before i woke up. the reason i found out was i got a ticket in the mail with the exact time she stole my vehicle and ran a red light, she then proceeded to leave with her new boyfriend that same morning to go to the beach. i moved back in with my parents and blocked all her contact info, this is kinda a fu and kind of a blessing i dodged a bullet thank the lord.

TIFU. By leaving my car keys by my bed.
