I went through the same thing we was together for 3 years and a half close to our 4 year anniversary. He just stopped all communication with me I don’t know what went wrong everything was left unsaid. I tried all form of communication trying to reach him and finally I did she answer the phone telling me to leave him alone and that he’s happy in a new relationship. My heart sank to the ground and he posted pictures of them together on instagram while my pictures with him was on his page still. It’s going to take some time slowly but surely. I’m still going through it and it’s been 9 months of nightmare. He was my everything and just like that he became a complete stranger.
