So confused

Me and my Ex have being broken for 3 months because he was moving away , and even though he was moving away we still was sleeping with each other and still found a way to be near each other , even though it was the wrong thing to do and because of this I’m still in love with him and he’s always on my mind , now he isn’t moving away and we are still seeing each other and sleeping together but the always staying other is his call and I always say yes and his mate always tells me that he is still in love with me and the only reason we broke up was because he was moving away and the relationship was at it’s peek during the time of the break up , when he is drunk he always wants me and always tells me he loves me but never when he is sober , and it’s all very confusing for because we haven’t spoken about what we are even though we are sleeping together and if it’s true that he loves me and that’s why he always wants me why doesn’t he just say something, as I want him back too , but I don’t want to say anything because it may push him away and I don’t want that , I sorta feel like I’m being used but sorta don’t at the same

Time and I’m just in a catch 22 , he is using me

Or not ??
