Idk what to do

Ok so I need advice on this situation I'm going through ok so there's this guy that I've known for like 5 years we've always been so close and told each other everything but we've never met eachother but he lives like an hour away from me and we tried that whole long distance relationship thing but it didn't work out because the was with another girl back where he lives and he hurt me really bad because I would say he was a big part of my life he was my everything at one point I would tell him everything and anything I trusted him with my life but then when we were in a "relationship" he wouldn't be faithful to me and then we stopped talking and then I tired talking to him again while he was in a relationship I was just asking if he was truly happy and that I will be here for him no matter what well it turns out that him and her broke up then he got another girlfriend which he has now and when they started going out me and him didn't talk for months and months and then he texted me out of nowhere saying he missed talking to me and stuff I mean I said I missed talking to him to and stuff but I wasn't trying to talk to him like that ok so time went on we kept texting eachother everyday and me he has dreams of us being together and that we are gona see eachother one day and all and like I agree with him and stuff but deep down inside it hurts me because I know he is with someone else and he just comes back like nothing after the way he did me and then saying he loves me and all that like I feel like it's not the same anymore I don't feel the same about him I don't see him as my pottential soul mate anymore yes I want him around but not like that but I don't know how to tell him that ..
