Complicated long distance relationship - thoughts please?

I was in love in my twenties with an asian boy, we dated for 3 years, he was my first ual partner. He left for an arranged marriage but still rang me for years.. My marriage ended recently. I contacted the asian for a different reason...we got talking, we still had feelings, we met up. We have been talking solidly for 2 months ..he says he still loves me, always has..he is still in the arranged marriage. We live 400 miles apart so can only see each other rarely..and then the is amazing. We tried not communicating - he did and gave in, I did and gave in. His marriage is bound up with his family, his work, his life...the relationship cant go anywhere...but means a lot to me being able to call and see him sometimes. I think he feels the same but am I being naive, could it just be that he is bored with his marrage and just likes the illicit ? I dont want to be just about .
