Advice needed.

Boyfriend of one year has been acting different. We have broken up three times last month, but instantly got back together. He takes hours to respond to messages (I understand when he's working or busy). He no longer calls me, he did yesterday (hasn't happen in months). He no longer tells me he loves me, misses me, etc. Every time we see each other he just takes me to his house. We haven't gone out on a date since July.... When I'm with him I don't know what to feel. I dont feel that he loves me. I feel like he's lost interest. I dont know if hes cheating because he has me on in his bio, posts videos of me, his friends know about us and so does his family, he always leaves his phone when he's not around. He doesn't when I grab it and go on his things. I dont know if it's just me?
