To be quite honest I was on Rochester's side when reading the chapters following the marriage proposal. I felt he just wanted to express his love, keeping in mind how Jane Answered that presents were generally thought to be pleasant things, he simply wished to give her some experience of being given said presents.
Rochester isn't trying to show Jane's inferiority to himself while proposing to her unlike another literary crush of mine in another less successful first proposal! Rochester sees Jane as his equal, even Jane herself says as much in her passionate speech before he tells her there's no engagement to Blanche. She says that she has not been trampled on, surely that means Rochester's treatment of her is considerate, or as much so as his nature will allow.
Jane's reaction to Rochester's gifts and comparing herself to Celine is just her Lowood training bubbling to the surface, IMO, the quaker-like notions drummed into her by her instructors at school.
