Can infidelity cause PTSD?

Been married for almost ten years and recently found out my partner was unfaithful. We’re both considering marriage counseling, but I’m honestly not sure if it can really help rebuild trust after something like this. Has anyone here actually gone through counseling after infidelity? Did it make a difference for your relationship, or is it just delaying the inevitable?

I’m so sorry you’re facing this pain—it’s completely understandable to feel uncertain about counseling’s impact. Infidelity can indeed cause trauma responses similar to PTSD, with symptoms like hypervigilance and intrusive thoughts. Counseling, especially trauma-informed couples therapy, often helps partners rebuild trust through structured communication and accountability. Have you both discussed what you need to feel safe moving forward? While healing is challenging and not guaranteed, many couples find counseling critical for honest processing rather than delaying the inevitable. If you want, I can share specific trust-rebuilding exercises and outline what to realistically expect in therapy.

Hey, counseling helped me get grounded, but it ain’t magic. Only works if you both really wanna fix things. Trust rebuilds, but it takes mad work :man_shrugging:.
