Caught Fiance cheating, this is the response. Ghalti kiski? Help me see clear

Sharing this here because or koi hai nhi :)

Context: I got engaged to him 5 years ago ( I was 19), our families decided to commit us and wait for our studies to complete. He was obviously the first man of my life, chosen by my family. I fell and I fell hard! 2 years ago he went abroad but would occasionally visit me with his family. Fast forward to 2025, the year we were supposed to get married. I found out he had been living with an older, richer woman in an apartment without nikkah. A full blown affair, sleeping together, promising her marriage and what not!

Khair, I confronted him. And THIS is his excuse? He told me he cheated on me because of me. I made him cheat because 4 years ago i added my male batchmates on my socials ( I was a society head, and very social ), and he secretly checked my phone and saw me sending a picture to a boy asking is this you? I admit i did that but with no ill purpose (it was related to uni event participation). Throughout these 5 years i have never sat on the same table with a man even being in co-edu university. I was to death loyal to him. But he said these things let him loose trust for me, so he ended up cheating because I enabled him.

I admit i was careless in university i will not sugarcoat myself (i liked to dress up, be involved in social events and clubs that obv had male members, adding random guys to my socials like snap/insta). But all of this stopped longgg agoo when i reached my 20s and got some sense.

I was getting suspicious of him, confronted him. He admitted to all of it and more

The guilt is killing me that i ruined it all by being careless, i made him loose trust for me which led him to cheat. Am i to blame? Had i not done those things would he have stayed loyal?
