<human>: My boyfriend and I have been dating for about four months and most everything has been going great. However, sometimes I won't hear from him at all for two days or so if we don't have set plans made. we're both busy, working full time with active social lives, so it's somewhat understandable. I haven't told him that it upsets me when i don't hear from him because I don't know if it's petty, I really don't want to be a naggy girlfriend. Even a text saying "hey, how is your day going?" would make me so happy from him on a daily basis if we don't get to see each other that day. Sometimes i'll even pose a question like that to him and won't hear back from him until late at night because he's with friends. am I being overly attached?

Summarize the given text in a few sentences.
<bot>: i don't hear from my boyfriend everyday, even when I reach out to him, and it upsets me. am I being unreasonable and should i approach him about it?
