The analyses of a text #3

The protagonist, Philip now works as a shop-walker at a lingerie store.

........................................
This was Mrs. Hodges, a little woman of five-and-forty, with badly dyed hair; she had a yellow face with a network of small red veins all over it, and yellow whites to her pale blue eyes. She took a fancy to Philip and called him by his Christian name before he had been in the shop a week.
"We've both known what it is to come down," she said.
She told Philip that her real name was not Hodges, but she always referred to 'me 'usband Misterodges;" he was a barrister and he treated her simply shocking, so she left him as she preferred to be independent like; but she had known what it was to drive in her own carriage, dear-she called everyone dear-and they always had late dinner at home. She used to pick her teeth with the pin of an enormous silver brooch. It was in the form of a whip and a hunting-crop crossed, with two spurs in the middle.

1. I'd like to know why it is "shocking," not "shockingly."
2. I'd like to know what "like" means here.
3. And I'd like to know if "they" means "Mrs. Hodges" and her ex-husband.
Thank you in advance for your help.
