What a long strange trip it's been

[MrBond]

IMO I think you've done enough soul searching that you know you wouldn't do anything that would hurt your W. In this case it might knock back all the progress you made so far.

Your W is just starting to open up to you and initiate things. Because of her low self-esteem, this might just knock her back into the MLC hole.

If you do feel the need to confess, then I would wait awhile longer until you two are on better footing.

Just my .02.
