Communication

Pointers on how i can improve our communication style . I been dating my leo since July 2017. He was all over me at the beginning but now he seem distance. We were introduced through his cousin who is my best friend. They've had a fallen out and i feel like that has affected us somewhat. Lately I realize how much i am smitten by him and want to be exclusive but i dnt know how to tell him bc sometimes i feel like he is into me then sometimes Not. He is moody. I am guilty of telling him i will fall back if i havent heard from him in a day. But he would reach out once i say that (Yea i know a bit childish but i guess thats my insecurities showing). I am like that only bc on New Years eve we spent some time together but later that night i also saw he was around his ex. I didnt say anything bc we are not exclusive but i wasn't feeling that. Still dont. I want to have a honest conversation with him and ask him how he really feel towards me and what are his intentions but every time we are together the timing is off. He's dealing with a sick child and dealing with the passing of his grandmother who he was very close to.
