Six months ago i break up with my ex, the reason is that she invited me to a party that i could't go, because on the next day i would go on an track day with my friend (this is my unique hobby), so i let her go without me, no problem at this point, i went to the track day had fun and i texted her, but didn't received any notice of her, so at this time i got really worried of what happened to her, so i asked to a friend of mine that went to the same party, he said to me that she went to a boys house (a guy that i don't fucking now) and slept thare, so i pick up my bike and went on her house, i waited outside for like 2 hours because she was not there,  when she  appeared  she  instantly  went to a "OH FUCK FACE", i asked her what happaned, she said to me that she only slep there because was to late for her to come home. I didn't trust that because she was with some friends, and one of them was with a car.
