Is my fwb falling for me?

We've been fwb for a little over a year. He came out of a bad 16 year relationship and we started this a little bit after that ended. Last night I was at his house and he started complimenting me on little things..my eyes, my skin and the sound of my voice. Hes always pretty open with me about what's on his mind and how his days go but last night seemed different. When we were finished he made the comment that I was "growing on him" and that he had a million questions and wanted to make sure I "passed the application process" (laughed as he said that). He said he finally realizes that his happiness means something to me and to "be patient" with him as he continues to work on getting his ex to finish clearing stuff out of the house. (She was living with parents, just got a house and they have a child together). He also kissed me before I left which has never happened before.

Am I reading into this wrong or could it be going somewhere?
