Must admit I would find it hard to distinguish between being humble and being overly nice through guilt. Did Sandi go into much detail here (can't remember the actual posting)? You're doing great BTW!
overly nice through guilt is all about that person... what's-in-it-for-me attitude... it's affected... not genuine... humbleness asks for nothing in return... expects nothing... you cannot fake it... that's why it's important to take time before believing words and even actions... because a faker can only fake for so long... a faker will fake until he/she gets what he/she wants (temp check)...
btw, CW2017--you are doing something my husband did during the early stages of my A... he knew for months before he confronted me... that was a big mistake... if he had confronted me early on, i would not have become so engrossed in the A... by the time he confronted me, i was fully in it... much too deep... by then it had become a compulsion... i know this isn't your thread, so i will stop here...
