Dude stop fooling yourself:
1) She was a plate, lived an hr away from you, you were noncommital, and she lied about being a virgin; what makes you think she was even 40% exclusive with you. There were probably days where your **** was touching the semen of guys she smashed on the same day,srs.
2) You in no way "alpha widowed" her, you guys were not in a committed relationship to begin with. If you were alpha she would have flown to another country to be with you per your invite. Being alpha is being able to lead yourself and those you care about, regardless of circumstances. You live with your parents and are jobless, you think you are close to her best option, hence why she left and tries to use you for validation. She may have seen you as alpha at one point but by the time she "started" talking to other dudes you had lost that title bro. She was not alpha-widowed but instead moved on from a beta failure. You have to look at it from a female perspective.
3)You developed one-itis for a plate, why do you even care about her.
Get over her, focus on yourself and never look back .
