I Am In a Long Distance Relationship

It is very very frustrating when your boyfriend doesn't talk to you as much. Granted I understand that we both have lives outside of each other but it just still frustrates me because I have other people who talk to me more than he does....I mean ughhh, he has even told me that he feels like he doesn't give me the attention that he should and then he just stops replying... Our video chat sessions are becoming slim to none..A part of me feels like I may be overreacting and the other part of me feels like I am doing all of the work. I really just don't know what to do
