our relationship was really short but we had really strong feelings for each other, he broke up with me because i was being needy, i wrote him a super long emotional message the day after breakup, no respond of course and i didn’t text him for 7 days, on day 8 i texted him something really casual and warm hearted such as wish him all the best… he replied me and told me he was just about to text me and he picked words(/something) i mentioned in the emotional message, i have heard ex won’t bother to read at all, but his respond tells me he read every single word, not go into details here but he even asked about something i told him while waiting him back(thats what people called EX neutral question respond), it just wasn’t his matter if we are not together… he was very warm there 
so his reply freaked me out, i acted really cold because i didn’t know what to do, and it turned out he thinks I’m not interested in the idea of getting back, i guess… we have few texts for 2 days but he became colder and colder, and indifferent in the very last texts… i asked him to go for a lunch(I’m always near his office), he answered no and explained the reason with detail, it was very cold, reply was quite a lot of words compare to his other texts
then i begged with long message on and off for 5 days. nothing from him for sure.
I know i made so much mistakes but english is my third language, at the beginning i never thought of googling how to get your ex back, so now I’m going on no contact, and its my day 6, hopefully it isn’t too late! does anyone begged quite a lot and still get your ex back after?
I really cherished the relationship, although it was short, theres something special about it… the chemical we had was so dramatic, i have an exbf of 5 years, this guy and i had a much stronger connection so i think its worth to have a second try without insecure
