Yes, this is a perfect example of gaslighting. The abuser puts the responsibility on you by saying, “I’m sorry you feel this way.” In doing so, he/she is not taking responsibility for the cause and is placing it on you to make you think you are crazy. By saying, “I’m sorry you feel this way,” he/she denies your feelings and, from a position of feigned superiority, expresses regret over “your” mistake.
