It's not easy to accept girl, he should cut all ties with the best friend of her if he's going to marry you. You see it's messy even if you two aren't married yet, what if you're already a married couple? Please you should talk this with your htb and please clear all that the things that you're...
Sorry to hear what happen to you, but don't be sad and move on. Don't waste your life on a woman like her, the're are so many out there that deserve your love. Enjoy your life you're still young you can find someone who you can spend the rest of your happy life. Anyway wish you all the best bro.
