Well this record was heavily influenced by what was going on with the band, specifically Richie and David. I think the song has got to do with them. David went through a divorce, so when someone leaves you feel alone because i know i did with the breakups i had. Then with Richie his divorce, his breakup with denise, his father's death, Rehab, so Richie definately felt alone. So Jon was basically saying you don't have to be alone me and the rest of the guys are here for you. Your other family(the band). hasn't left you. You don't have to be alone no more. At least thats my take on it.
