Should I be alarmed by his slow text response?

trust me when i say guys are never worrying about this kind of stuff as we girls are, as a result they don't find it necessary to text back all the time. if they are invited to do something, however, the reason why he didn't text back was probably because he was busy! i ALWAYS think about this too, and then i think to myself: remember the times that i was doing something, and i checked my phone and someone texted me like two hours ago? don't you think they were worrying whether i was ignoring them or not? remember, everyone has things to do, and sometimes you can't get back to people right away.
