a few months ago my ex broke up with me, in the first place he asked me out normally, i said yes and we dated. i used to feel very insecure with him but i really liked him, a few months later he broke up with me saying he cannot emotionally invest his time on me, after a few days he asked out my friend who is very close to him, they both were like sister and brother and she is 7 years younger to him, inspite of that he asked her out. she knew that i was deeply hurt when he broke up with me but she still accepted him and they both are now in a relationship, that guy later told me that he loves her even though she tied him rakhi and that everybody kows them as sister nad brother, she is 15 and he is 22. both of them have hurt me very deeply. the girls parents even know about her relationship with him and are okay with it. her father even started deciding their future with her boyfriend!!!! this is pissing me out. i cared about him so much, i gave him whatever he wanted and he cheated on me with his sister like friend!!! i am very sad. all these days i was thinking they wont last but the girls family is planning her future with him. i know this is a toxic relationship but i hope they breakup and get their karma, i have my entrance exams coming up, i have already fucked up one of it, my career is falling apart. i am totally deviated. it would be of great help if someone helped me, thank you and may god bless you. also that girl(15 year old) is very immature and innocent type. even my other friend says that he is being possessive about her and is distracting her from her studies, do you think they will last?
