Does returning to sins after repentance indicate that the repentance was not accepted?

Question:
What is the ruling on one who commits a sin, then repents and feels remorse, but after a period of time returns and commits that same sin? Does this indicate that the repentance was not accepted?

Answer:
What indicates that the repentance was accepted, but it also indicates that Satan is still adorning the evil for him, his self that commands evil. So he should repeat repentance; whenever he sins, he repents to Allah, seeks help from Allah (Mighty and Majestic), and stays away from the causes of sin, the causes that lead him into sin. Yes.
