So he was working away and he and OW were planning their future, so it was a full PA/EA. You saw the messages, pictures and videos. What a brutal betrayal.
@Ariel896, you are not being unreasonable for feeling unsettled about this news or inadequate for being unable to forgive and trust. Infidelity is shattering and can cause PTSD. Swallowing such distress is massively corrosive.
Questions:
*After discovery, what support did you have to express your heartbreak, grieve, and recover from your injuries?
*What work did H do to ‘fix things’ … to make himself a safe, trustworthy partner and to help you heal?
Did he:
(1) end the affair immediately and cut contact with OW in front of you?
(2) examine his character flaws that enabled his cheating by accessing IC or plugging into websites/readings?
(3) show patience and compassion whenever you expressed your tears, anger and asked questions?
(4) provide transparency with all devices and statements?
(5) tighten his boundaries with other women?
@Ariel896, if he had been truly remorseful and empathetic to your suffering back then and beyond, he certainly would be sensitive and caring about your current unsettled feelings. He is returning to the same lifestyle he had when he previously cheated, and is telling you to suck it up. That is callous and contemptuous.
Many betrayed partners find years later that the damage is too great and wounds too deep to recover from — that trust and peace of mind cannot be restored. This is entirely valid and understandable, and would be a legitimate reason to end things now. In your shoes, I absolutely could not contort myself to be okay with his working away and stay married. If you force yourself to do this, the damage to your emotional health could be catastrophic. [As an aside, I would never have attempted to forgive my H for so heinously abusing me by investing in and planning a future with another woman while I was at home missing and trusting him.]
I would consider seeking IC, not to steel yourself to withstand his working away, but rather to strengthen your self-esteem and formulate an exit plan.
