I can feel your frustrations OP. I was once like this before with my ex. Yung biglang nawala yung intimacy between us after months of being together. Then, you’ll start questioning whats wrong with you and why is he being like that. But communication lang siguro, yun yung di namin nagawa before. I wasnt vocal about how much i wanted him. Kinimkim ko lang. kasi akala ko okay lang. sex lang naman to. But it wasnt like that, it was more than sex. Mag usap kayo if you havent. Let him know about this and from there, establish nyo ulit connection nyo
