I believe there is no such thing as “self-esteem.” All “esteem” is borrowed from another, be it a parent, a friend, a sibling, a co-worker, an acquaintance, or God. If we put weight on the wrong source, we will become a “Born Loser.” We need to select carefully who we will allow to define us.
I do believe in most situations, the groom here is on the wrong side. At this point in the marriage, the groom is to be on the bride’s right. Just being picky, I know.
You are a month early. Sorry for the reality check!
