does God get disappointed with us?

ok, so this may be a long one, part from a book i'm reading:

If I ask someone, 'does God love you?' Most people would answer yes, of course. He has to love me. He made me. However, if I change the question and ask if God ever gets disappointed in you, I get a much different answer. Most, I'd guess over 90% of Christians would say, 'Oh, yes- There are many times when He is disappointed in me'. It is this disconnect between saying that I believe God loves me and yet not feeling unconditionally loved that challenges the modern understanding of the Gospel. The sense that God can be disappointed in me reveals the performance ideas still resident in my theology. On an emotional level, when we've disappointed someone we care about, there is an unsettledness that goes on inside of us. Depending on how sensitive we are, it can get pretty intrusive and most of us feel like we need to do something to repair the relationship. sometimes this sense of obligation motivates us to make it right or apologise or whatever because we want to feel at peace again inside; sometimes the motivation is self-serving like with those who cannot tolerate conflict and negative emotions. Either way, this feeling usually moves us to repair the relationship. Now while this works fine in human relationships, it is absolutely mistaken when it comes to the Gospel. Because, for disappointment to exist, there must be some sort of prior expectation. We live with appropriate expectations all of the time in human relationships, but the Gospel says that Christ has fully met ALL the expectations and requirements of God on my behalf. If there are no expectations, then there can be no disappointment.

So what do you think? I was brought up all the time being told (in?)directly that I was never doing enough for God and (perhaps even unintentionally?) that He was therefore disappointed in me (as supposed to an unconditional guilt-free inabilty to be disappointed crazy love)
