I wan to bond with my cat?

I am Natasha, I am using my boyfriends account, and I have a 10 month old kitten who was fixed last month, and I feel like he doesn't like me. I try to be really gentile and loving and when he cries I try my best to make him feel better, I get on the floor with him and try to play, Im not sure what Im doing wrong or what to do, I want him to come up to me on his own, he only comes up to me and is affectionate when Im on the toilet...whats that about?????
