Is it illegal if I stay wth friend on tourist visa nt hotel

I asked for attestation but my gf don't want, she has AS. Will police checkup hotel where I did booking and arrest me if I'm not there? She said attestationit's only if I stay 3 afraid I may get rejected for it's not easy to get visa from Bangladesh after terrorist attacks. I really wanna see her but she's autistic and don't understand the risk. Please let me know. Thank you
