Time heals. Forgive him and forgive yourself. Usijilaumu sana; watu wengine huwa wanapita kwenye maisha yetu kutufundisha tu vitu fulani; he served his purpose well; let him go in peace. Don't curse him, don't wish bad/ evil on him. Usikate tamaa ya kupenda; kuna siku utampenda atakayekupenda. You are what you choose to become; not what has happened to you; don't dwell in your past please.
There are plenty of good men out there; you shall bag your's one day. Even if he won't apologise to you; forgive him for your peace of mind; don't wait for his apology; some people's consciences are dead.
Hey it's never wrong to love a person genuinely. As long as you loved him truly and your intentions were pure; you haven't lost anything darling. Hold your head up
