Confused! Should I move on or stay with this man?

I’m a 23 year old Girl dating a guy who’s 29 years old. We’ve been dating for 2 years now…..look I love this man like Crazy and he says he loves me too….but the thing is he doesn’t show me Love, he’s so damn cold…He will never phone n ask how my day was and he takes 2-3 hours to reply to my messages…I met his mom once and never again. Look I don’t even know where my boyfriend lives or with who he stays. I see him 1nz every 2weeks 2-3 days before its time to come see me he will act all nice coz he knows its time to come…wen he’s with me he’s very loving but when he goes home he’s so cold with me….he got a baby girl an the baby mumma stays 20min away from him he’s always there coz I will find thing of the child in his car but I dnt mind I knw I would love her so much….but the thing is I’m his gf why doesn’t he tell me when his with them why hide it from me…to yol think he’s busy cheating on me with baby mumma…coz I feel like this man is only using me….but then again why would he drive 2hours to come see me. I’m so damn confused should I move on or stay with this man….
