Is it normal if he doesn't put much thought into what he's doing?

So I have confronted my man about being into me or not. Of course, he says yes or else he wouldn't be doing any of the things he's been doing. But he's so vague because when I point out the things he does do that make me feel he is interested and let him know WHY i think those things make me feel he is interested, he just goes "I guess" or "I never really thought too much about it." I'm just concerned because if he is doing all the right things to make me feel like he is serious about me, yet, apparently doesn't realize how important these things are to make me feel better, then does that mean he ISN'T really interested in me? So like a few things he does that assures he's serious about me: he talks about his work, his friends, what's going on with him at the moment; he introduces me to his family and friends, some met me and the rest know of me; he includes me in activities he likes to do; he does his best to make time for me; he asks about whats going on with me; he does ask me for advice and considers it. So if I were to tell him, "you know I like how you take me to play golf or softball, shows you really are into me you know...?" He'll go "um yeah I mean I guess..." -_- great so I guess all these things you are doing right don't mean as much as they should mean? What is this exactly supposed to mean? He is still serious about me regardless if he puts thought into it or not?

Guys can come off as sort of clueless and this is an example of it. He doesn't realize that yes these things mean something. He has said he wouldn't do the things he does for me with just anybody. Or he's pointed out "Ive taken you out with my sibling, and my family knows about you. How is that not taking you seriously?" Then when I point out other things like the whole "taking me out to play..." he won't think much about it as if he'll do that with anybody. If I tell him "I like that you're comfortable with me to talk about your work and whats going on" he'll probably say "well you asked about it so I just answered you" or "well I tell other people,too, soo?" I don't get it and I don't get him.
