I don’t understand

Hi

So I have been dating this guy for almost 3 months now and he’s been great in almost every way. He lives about an hour away from me and so we have been spending the weekends together, which seem to get better and better every time. The past few weeks though he has pretty much stopped calling me or texting me during the week, and so we haven’t been talking much besides on the weekends unless I call him, and even then he just seems too busy or just not really into talking most of the time. But he does pick up little things for me or for my 2 girls during the week and when I do see him, it doesn’t seem like he sees anything wrong. Also, right as we first met, he had just been dumped by a woman he was starting to really feel something for, and it was pretty hard on him- feeling betrayed and lied to. She did try to contact him on social media a few times about a month or two after she left him and he has said he’s blocked her since and deleted her phone number. And the only reason I know this is because he came out and told me. I guess I am just not sure what to think about the whole thing and it makes me feel shitty a lot lately during the week.
