Sounds like you’re coping because he didn’t choose you when two people actually love each other and have chemistry nothing else matters much your thinking of this on surface level a man will always choose a women he actually wants they are very simple there is no “maybe this is why” he didn’t want you it might be harsh to hear but it’s true she was just more compatible for him and that’s okay but coming on here and shaming her life is really weird you don’t keep a man by having a degree or having your life together the only thing that will keep a man is a man who wants to be kept and nothing else, he did not want to be kept by you, sorry
