But I can't rid myself of the idea that it is a ploy to placate and leave me. He's given zero indications of that but going from reactive to accepting and loving scares me so much. I genuinely trust in his love and change and he's shown the effort, but sometimes I even worry that he's doing it so he could murder me or leave me somewhere and have plausible deniability.

How do I deal with this? I keep my thoughts to myself but I don't want to feel like this. How can I trust that my husband genuinely wanted to improve our marriage and has done that, without the doubts that it is a long game in order to leave me? He's happier, I'm happier, but I am so worried and I hate it.
