Any suggestions/ ideas ?

Hey there!! So I recently posted something about my bd searching this women on tiktok and following her on every social media, I confront him and he’s story was the some coworker number he had but the guy changed the number like “what?” He has her on WhatsApp cs I seen the pic I search her on fb and it’s the picture soo I believe the if someone else was using the numerber like why followed her and have her on WhatsApp he recently followed her on tiktok, I search conversations call logs, no conversations but 2 outgoing calls for 1min back in 2022. Now should I just message the girl?? And yes, what should I said??
