"A short period of exquisite felicity followed, and but a short one. Troubles soon arose. Sir Walter, on being applied to, without actually withholding his consent, or saying it should never be, gave it all the negative of great astonishment, great coldness, great silence, and a professed resolution of doing nothing for his daughter. He thought it a very degrading alliance; and Lady Russell, though with more tempered and pardonable pride, received it as a most unfortunate one."

Focussing on who values Anne and who doesn't for this GR, I find that the Captain falls in love with her qualities quite quickly, but for a short time. The fact that it was mutual, that she loved him and valued him too, did not really help matters with Sir Walter. It's interesting he doesn't actually "withhold his consent", so it mustn't have got too far before it was stopped as a general bad idea. Anne may have expected her father to have the opinions he did, maybe?
