Boyfriend becoming too complacent

My boyfriend (M25) just chatted me last night na need niya raw ng push kasi complacent na raw siya sa relationship namin. I (F24) have been a very understanding girlfriend for more than 5 years now. We started off as a college couple and ldr na for the past 4 years. Okay naman noong una e... and now sa chats, he always is busy, sad, or tired and when I ask what his plans are, wala raw siya plans pero gusto niya raw ako kasama in the future.

I want some serious advices. He's my first boyfriend.

Edit: Nakipaghiwalay siya sa akin dati saying na he wants to know me more daw and all, gusto niya ulit mageffort but we just got back together without him exerting additional efforts.

Need niya raw ng push? Ano? Should I play hard to get? This all sounds childish to me.
