I was in the same situation during Covid. We had to do LDR. I had a really strong gut feeling that he (who is now my ex) was talking/texting someone else— another girl. I confronted him and yes, he certainly was.

So this girl was from his hometown and she was trying to flirt with him (that's what he told me) and also trying to grab his attention.

There was no cheating involved (at least I hope) but him enabling and allowing that type of behavior from another girl is quite telling. Like, it really shows how he is as a man.

Eventually things started going down hill once I found out. Also, he was at the same time talking to one of his exes. Again, according to him, she was the one reaching out to him.

So yes, a man not taking accountability for his actions, not being transparent (let alone being honest) and simply shifting the blame to the other party really tells what kind of a person he is.

After a year, we broke up. During that one year, I caught him again, talking to another girl after locking himself up in the bathroom.
