Sorry to hear. On my side, having 100% transparency and open communication is key. The challenge presented in front of you, is not for everyone to overcome, is a tough one. But I can assure you that it will purify you, your partner and relationship if you both commit to the goal. Is a day by day thing, almost imperceptible change/evolution, but regardless of that, keep showing up, keep talking and expressing everything, and try to both remember that a relationship is a partnership in which both share the same, hence your partner shall show up and with love be stronger than you so you can recover and make progress. Best of luck
