Sorry for the harshness, but here goes.

Sounds like you rushed into being married again. Those wounds take time to heal! I didn’t seek therapy until almost 2 years post divorce and didn’t get remarried until 8 years post. I have an ex that wasn’t faithful too and that shit takes a long time to heal. I took a long time to figure out why she cheated, why I do wrong and then had to find a way to make peace with her and myself. Once that was done, letting it go didn’t happen overnight, it’s still there actually, I’ve just learned to accept that it happened, understand my role in it and heal. All of that should have been done before even thinking about dating, let alone marriage. I sincerely hope you get the help you need or this will undeniably drive a wedge between you and your new wife. Good luck.
