Work around her past dissapointments
In his post Won’t get fooled again, Seth says:
The reason that people don’t believe you isn’t that you’re a liar. The reason we don’t believe you is that the guy before you (and the woman before him) were unduly optimistic hypesters and we got burned. We believed, we leaned into it and we got stuck.
I think many women enter marriage with a similar situation; having been fooled by boyfriends, they are concerned about male motives and sceptical of claims or promises made by their husband. To paraphrase Seth, it’s not that she doubts you because you are a liar. The reason she doubts you is that other guys have made claims they did not live up to and she got burned. She believed, she went with it, and she got hurt.
The solution? Seth nailed that with “Make different promises, or even better, do, don’t say.” Let your actions speak for you.
What doesn’t work? Complaining that you’re being penalized for the wrongs of someone else. Yes, you are, and no, it’s not fair, but this is in the realm of feelings and even if she agrees with you it won’t change how she feels.
