The lyrics from most old songs are so simple and easy to interpret. I think its pretty clear, the speaker thought his significant other was cheating on him so her dumped her in anger. Now regrets it and wants her back, so he is trying to change everything back.
Not sure if it was intentional, but by using "change" for both the forward and backward change, the speaker is implying that he thinks it will be just as easy to undo the changes as it was to do them. He made "all those changes" quickly ("I didn't stop to think"), and now he thinks he can simply change things back and time will rewind. Instead of addressing her feelings, he is just says "I'm wrong", so I'll just change back and everything will be fine.
