Should I hang on

Hello house, I'm writing to you in the hopes that I can get some clarity as to if what I am doing is a good thing. Recently my ex boyfriend of a year and a half has contacted me since we broke up 8 months ago. We left on a bad note. Now he has written to me via text and has said so many sorries and how not one day has passed that he doesn't think of me and miss me and my parents. Well a little fast forward so I don't make this too long. I melted with these words and they were words I had needed to hear for a long time. finally giving me peace that he had that love. that he wasn't a cold jerk after all. Anyhow now I've agreed to see him. I see him about 3-4 times a week, great company, great s.x like old times, but he doesn't want to get back together with me, well so when I asked him why, he said he wants someone younger than him eventually as I am 40 and he is 34. but he says he doesn't want a relationship no. I want to be with him as we are perfect together! He says he loves me all the time and I say it back, he says I'm his best s.x ever and I feel the same way about him...what do I do ??? Do I hang on to this and he'll eventually come around ?? Or is he taking me on an emotional ride to no where ?? HELP !
