Guys, Is this typical male behavior?

So my boyfriend and I have a pretty good relationship, however the other day I noticed a pattern in his behavior at times. Somedays when I've already been gone all day at work and I come home he just sits on the couch, nose deep into a game on his phone, basically kind of ignoring me. I give him space/stay quiet for a good 20 minutes before kindly asking him in a calm voice if everything is ok which is fine, it's in his tone that bothers me when he responds. His tone almost comes off as irritated in the way he said "I'm just playing my game" when usually he is pretty talkative with me. He does have MS and I did notice that he seems to get this way when he isn't feeling good either from his MS or when his allergies are bothering him, so I keep to myself/distance myself entirely, then he starts talking to me again. Why do guys do this instead of just saying through don't feel good etc? It makes me nervous because in past relationships, when I dated a guy that was like this, he turned out to be very narcissistic, etc. Although I can't see my current turning out like this, I do wonder why males seem to reply in such a tone that suggests they are annoyed. It's like you are sick of our very presence, at least that what it seems like when they respond in a tone like that so I just keep my distance/give cold shoulder when he's like that, then the next day he will drive by my work when I'm keeping my distance. It's odd to me, but is this normal?
