poetry explication for "Scaffolding" by Seamus Heaney?

Commentary:

The simple but dense "Scaffolding" is a love poem. The image of a building under constructionrepresents a relationship that two people build over the years. Initially, the building needs externalsupport, but eventually it stands on its own. Even the formal structure of the poem supports the ideaof sturdy architecture: five neat couplets with perfect rhyme.

In the lines "So if, my dear, there sometimes seem to be/Old bridges breaking between you andme/Never fear" the speaker characterizes conflicts between the partners as a natural part of a long-term compact. Crutches they once used to stand on -- half-truths told to protect someone's feelings,or other ideas or expectations -- can be discarded; the bond the two have established will withstandthese losses one by one, because "we have built our wall."
