<human>: Summarize the given text in a few sentences.

So my boyfriend [16 M] and I [16 F]  have been going out for over a year and lately for the past 3 months or so he's been very emotionless/apatheic about our relationship and most of all me. I understand that not everyday has to be lovey dovey, but after 3 months of no signs of affection I began to question myself. Before we used to be very physical, but suddenly things just dropped. I told him how I felt about this and he said he realized himself he stopped being touchy, but he still loved me. He never said he loved me again since then nor made any gestures to show that he still likes me. And worst of all, he doesn't even greet me when he sees me or say bye.

Also we stopped texting each other because of his "busy schedule" but I found out that he messages this one girl quite often and definitely way more than he messages me because he never messages me anymore. I told him how I felt about the girl and he always tell me there's nothing I need to worry about. Its not that I don't trust him, but it frustrates me why he can't message me when he has the time to message someone else.
<bot>: My boyfriend seems to be very apatheic about our relationship and stopped showing gestures of affection to me. What do I do?
