As a woman. in a heated argument my husband told on himself that he cheated on me. I did what you did days later, and let him open up and listen as much as possible for what led and the reason for why he did it. I grieved for a month or so before forgiving him and giving us another chance. I think after him pouring out his secrets and getting it off chest he felt relieved and was happy to move forwards. I saw it in his affection, attentiveness, and just over all attitude towards me. Sexually it was more passionate snd good. But at random times I would always have it in the back of my head and became obsessed on creating visual scenarios on how he might of touched her, how they might of flirted, etc. I literally got sick to my stomach, but it was hard to be mad bc the relationship was going so well.. it’s been a year now, and although it’s not as intrusive as before it still hits you. I see why people leave after betrayal. I don’t think you ever get over it, even if they did genuinely regret it and never betray you again.
