She had dreaded him, winced before him, succumbed to adroit advantages he took of her helplessness; then, temporarily blinded by his ardent manners, had been stirred to confused surrender awhile Timely you suggest this means she consented.
But this is at a point when she is looking back. She is referring to the circumstances that lead to her being with him in the first place and getting into his orbit I believe.
We learn she had been seeing him for three months.
In the lead up to the rape she was on a horse with him while he supposedly was taking her where she needed to go. In the quote you gave she may also have blamed herself for taking up his offer of accompanying her and getting on the horse with him.
When she realised he had been meandering on the route on purpose and not taking her to the destination, she tried to get away.
How could you be so treacherous!" said Tess, between archness and real dismay, and getting rid of his arm by pulling open his fingers one by one, though at the risk of slipping off herself. "Just when I've been putting such trust in you, and obliging you to please you, because I thought I had wronged you by that push! Please set me down, and let me walk home
He said they were lost and she could only go once he had made sure where they were, meanwhile she was to wait while he did this. He gave her his coat and she sat down on a pile of leaves. The horse stood nearby.
Before going he he let her now he had given her father a horse and her siblings toys making her feel obliged. She was crying in desperation because she realised he liked her but she did not return the feelings.
He went off on a walk out of the woods to get an idea of where they were.
She was eextremely exhausted and fell asleep on the leaves, Then when he came back she was quite definitely still asleep.
He knelt and bent lower, till her breath warmed his face, and in a moment his cheek was in contact with hers. She was sleeping soundly, and upon her eyelashes there lingered tears.
Then we learn her guardian angel had not been with her.
What happened to her is compared to the rape of peasant girls in the past.
After that we learn she was no longer a maiden.
We are told that she had realised the serpent hisses where the sweet birds sing.
To me it seems as though what happened to her was not consensual at all.
In the next chapter when she meets him again he tells her thought no means yes.
He admitted he had done her wrong.
The word seduction was mentioned as a modern idiom during the radio discussion.
