It's been 2 years since my ex girlfriends and I broke up. Till this day, she has never told me the real reason, although I have no feelings and desire to get back with her as I'm succeeding in college and on a great and productive path. She has tried to contact me twice before but I just ignored it and went about with my life. Yesterday, her new boyfriend requested to follow me on Instagram out of nowhere. I don't know him personally, and neither does he—besides only through my ex or her friends. I'm happy of my current life. Just wonder why he wants to follow me and whether if I should just ignore it like before and continue being productive and successful. Thanks.
