This is quite a common thing with men I find. Everything gets downplayed because most are really confrontation-averse and poor communicators. Now personally I would bring it up, outside of obviously wanting an answer I find these things only explode out of them at a later date and leave you feeling blindsided. HOWEVER, expect 1) for him to feel cornered and be very defensive, through no fault of your own it may not be a productive conversation and 2) for him to tell you something that may be hard to hear.
On the former, I'd maybe give him a heads up via text earlier in the day for a discussion when you get home? As with things like this they never seem to respond well in the moment. Have a response ready for why you're "stalking him online" or similar though, they always seem to play that card. On the latter, I do think you just have to be brave, forcing men to be honest about whether they want to be with you has never caused a breakup, only sped it up, which in the long term is the most beneficial thing.
