This specific person and I were fwb, that became roommates. During the time of us being roommates, things were up and down, we fought a lot but cuddled a lot as well. One thing remained constant though, that at the end of the day, we still have each other. We became each other's person. We ate dinner together almost everyday. Do things together, watch movies, go around the city biking. He then felt that he wanted to try and date officially. This all remained the same til the lease ended. 
He wanted to move out, and see how things go if we were not forced to be together. Now, he realized he wanted the freedom and take things slow for us. This is devastating for me. He barely wanted to hang, and if I become clingy/ needy, the more he goes away and not talk to me properly. I am really afraid that he would find other girls. I am afraid if he doesn't wanted to hang out with me. I am so afraid to lose him. At the same time, when he rejects me, I feel bad and fights with him. I wanted this to work, but I feel like im letting my resentments grow. How to attract him back ? I understand that I can only attract him with kindness, but with him being rude at times, it's hard for me to remain calm and kind. 
I do want my person to be back. Spend time, cuddle, watch shows. How to clear the resentments, and not bombard him with demands to come meet me. I need patience. please help.
