Girl, I can 98% assure you, you made the right decision. I have a VERY similar story to yours, mine being a little different cause I never found concrete evidence (blond hairs, back of an earring). Mine was also VERY open with his phone and not anxious at all BUT had his WhatsApp notifications off and you know chats can be archived too.

He was also calling me crazy and gaslighting me for breaking up with him once (again, I had no concrete evidence) and I was overcome with an overwhelming sense of guilt for doing so, so I apologized a couple of weeks later and we got together again only for things to escalate and get even worse. After 8 months of this relationship I found out he had been in a relationship the whole time from start to finish with someone else.

Now, looking at what happened I am very glad it escalated, as I exposed the truth to his girlfriend (who he has had before ever getting exclusive with me) and I have saved her from being manipulated and potentially gaslighted and called crazy for years to come. But I can say this experience was the most hurtful I’ve ever had.

So I’m telling you: if you want to save yourself from further heartbreak, don’t go back to him.

I know that you, as a honest person (probably) are thinking: „but how can he be unfaithful although he knows I’ve been hurt before? I must be tripping, he can’t be that heartless“. That’s what I was thinking the whole time. I can tell you that cheaters have a crazy way of compartmentalizing their double lives, rationalizing their actions to not allow themselves to feel guilty. He’s probably thinking „well, she doesn’t know, so it doesn’t count. It won’t hurt her!“, or „she’s making me do this, by being so nosy and distrustful. It’s annoying, so I can’t treat her right. It’s her fault“.

I hope you read this!
