Is this relationship worth saving?

Background story. We had been together for 6 months but for the last 2 months everything starts to go from bad to worse. We don't talk much and we even act like strangers in our school.
Last week he actually sat me down to have a talk about it. We just came to a conclusion that it is because of our lack of communication and trust and we decided to work it out again. I asked does he still have feelings for me, and he said he is doubting his feelings for me. To me I kinda know that if he doubts then it is a no. But he never went into details. Is it worth saving or am I just being in a one sided relationship at this point?
