Does Allah accept the repentance of a wife who betrayed her husband, then regretted it and repented, and will He conceal her (sin)?

Adultery is one of the most heinous sins, but Allah accepts repentance and rejoices in it, and replaces bad deeds with good deeds. This is achieved by abandoning the sin, regretting it, and resolving not to return to it, while concealing one's own sin. Suicide is one of the gravest major sins, and a believer does not despair of Allah's mercy. Remain steadfast in your repentance and do not pay attention to the whisperings of Satan. "And whoever fears Allah - He will make for him a way out and will provide for him from where he does not expect. And whoever relies upon Allah - then He is sufficient for him."
