My boyfriend doesn't talk much with me anymore. Is he bored or lost interest in me?

Guys' opinion preferred.

We have been in a relationship for almost 3 months.Everything went well.We called,text and met each other often.Now,both of us are busy so we can't really see each other.However,I definitely expect him to talk like usual.I asked him and he said I have nothing to worry about because he still feels the same way and loves me a lot.He does text me every day but It is just like "don't forget to take your lunch" or "take rest baby" that's it.I feel like he is trying to distance himself from me.Is he being comfortable with our relationship or he has lost interest but afraid to tell me?
