The original sentence: "The wedding can't take place. I declare that there is an obstacle. " ...... "The wedding has been suspended, and I can confirm the assertion just now. This marriage has insurmountable obstacles. "

Jane Eyre's cousin wants to marry Jane Eyre, because Jane Eyre is independent and strong, and can be his assistant when she preaches in South Asia. More importantly, Jane Eyre's cousin doesn't love Jane Eyre, so he won't let his feelings affect his missionary work.

Jane Eyre's attitude is of course a little contradictory, but in the end she can't let go of Mr. Rochester, so she refused her cousin's proposal.
