Would you please elaborate on the meaning of this sentence? It's a bit vague to me.
It's not so much that I don't want to go, but I just haven't got time.
Although using "It's not so much that ..." suggests that at least a small part of him doesn't want to go! If it had said "It's not that I don't want to go", then I would agree that he did want to go.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
