"Bad texter" - truth or a red flag?

I've been dating a guy, who's very sweet during the dates and he seems like he's enjoying my company and he likes me. But I have the exact opposite impression over texts. He answers very shortly and dryly, sometimes he doesn't answer for hours or even days.

I decided to talk to him honestly about this and I told him that it bothers me and that it makes me confused. He told me that he's sorry, that he never had an intention to seem distant or dry, it's just that he's not used to texting a lot. And sometimes when he's busy, he sees a message and then forgets to answer, or something like that. But he said he's sorry.

I don't know whether or not to believe him. Maybe after all he's not that into me? Or there really are guys who might like a girl but still don't text her that often?

Update: I just found out he has a girlfriend :) so girls, please, when you get mixed signals and when you feel confused, trust your intuition, he's probably a jerk :)
