My Ex Bf - Advice Please

[Smiler5]

Looking for advice here!! I split up from my bf last year after nearly 3 years. I was devastated. I met a guy 3 weeks later - completely rebound but amazingly we are still together (not too happily at the mo!) despite a lot of things. However, my ex and I are still in touch by text a lot - have met up a couple of times purely in friendship and spoken on the phone. Sometimes we can text from early morning to late at night. I still love him and miss him dearly but he says that he doesnt love me anymore. Thinks we should stop this and try to move on - but on another foot says he does miss me and thinks about me. Tells me we have a connection! He isnt involved with anyone i know but im totally confused. Should I just leave it alone which i know deep down is probably the best idea but on the other hand - love hearing from him! HELP!!
