I was in a relationship with this guy for 3 years. This year in jan we broke up this person was my first. I loved him so much when we break up comes to find out that he was cheating on me with a girl from a diff college ( i was in high school i just graduated) while we were dating some months past and i realized that i didn’t get a reason why we had broke up so i talk to him about it i told him how he was my best friend and about how he left me ect just spilling out my feelings. After that his new gf finds out that we were talking again ( not sexual just as friends) so she blocks me in every social media possible i mean Facebook, snap chat , insta all of it so i was upset that she did it so i leave it alone few months later like in June my phone flashed it says the persons name as added you on Snapchat my heart dropped and we talk come to find out the girl is pregnant with his baby my heart sunk to bottom of my body i was heart broken i still thought we could make it work some how are at least be friends he is the only person that know that i suffer from depression and suicidal thoughts so u messages him yelling him that I’m having an moment and that i need him to talk to me no response i just wanna know how can i get him out of my mind
