How to heal from this
We are both in our 30s. This is the second time he has cheated on me (f). This time he lied for a month straight. I asked him outright several times and he said no. I felt like something was off so i was asking if there had been anyone else. He told me no. We were intimate and I asked him before we were intimate because I could still feel like something was off. Shortly after that I found out through the girl he cheated with. She originally was vague about it and said he was trying to flirt and that she shut him down. I asked him he denied it. A couple weeks later I aksed her for more details. She gave me more details and I told him I had proof he denied it for 3 hours and told me I probably made it up. And then started accusing me of lying about random things. He finally admitted to it.
Then I found out more details that she had kept from me. And I called her out on those. I asked him to see their messages and they were deleted. So i aksed her. She sent me all of their messages.
But i asked him why hed lie. He said "i thought i was protecting you". I told him that lying to me is not protecting me its protecting himself from consequence and accountability. I also said by holding that narrative he is only causing more trauma and making it harder to heal.
I was still working on rebuilding trust from the first time of cheating in January. The second time happened in the middle of May and he didnt own up to it until the end of june.
I dont know how to recover and rebuild the relationship if he is continuing to say that he was trying to protect me by not telling me the truth.
