Why does my ex still offer to do favors for me?

My boyfriend and I recently broke up because he moved to another country. Other than that we have no issues and the breakup was amicable. Recently, he started asking how I am after weeks of no contact. And we've been talking since but of course not in the sweet way as boyfriend girlfriend. He also offered to help me look for cheap flights for my vacation. However, he's not mentioning about our relationship or the breakup nor the future. What's on his mind?
