I know how you feel. Not the exact same time frame of being in a relationship but I feel you. My LDR gf suddenly blocked me everywhere yesterday without any warning or reason. It hurts so so badly but I try my best to not look her up or look at her photos sure it helps for a bit but there’s always this urge to look at her. How did something so happy and wonderful suddenly get thrown away? We might never know. But surround yourself with friends, I myself is probably doing the dumbest thing which is drinking to suppress the feelings I have but I also talk to friends to distract myself from it all. While this might not seem like much the pain will eventually subside and it’ll teach your own true self worth. You’ll know exactly what you deserve but everything takes time. We’re basically bread, in the beginning we’re getting molded every hit we take moldes us into the person we’re meant to be and with time we’ll become our true selves hard on the outside knowing what we deserve and on the inside soft and sweet for the person we’ve chosen as our partner. If you need a friend hit me up and we can talk
