Is he really looking for something serious?

I have been in the talking stage with this guy for about a year and a half now, reason being is we have been through a rough start but decided to work on the issues regardless, with that being said we have worked on those issues and things have been going well for a while however he still isn’t taking the next step.. I bring this up to him however he fails to give me a solid answer, am I wasting my time? Is he just playing with me?
