Do boys eventually miss you?

my ex boyfriend and i ended about three months ago. he took no time to heal and jumped into a new relationship and cheated on her with another girl; she stayed with him despite it, but he came to me for comfort afterwards. will he ever come back to me or realize what he lost?
