My boyfriend hasn't returned my message since the Spring Festival?

From what you said, I guess he has a family, right? You are his secret love. He has been afraid of others knowing, you should understand. As the saying goes, onlookers see clearly. He wants to get rid of you now. I'll be with you when I have the chance. You put your heart and soul into it, but he did it once and for all. Maybe he didn't mean to play with you, but he doesn't care about you at all. I suggest you take care of yourself and stop here. Do not contact him again. If it's over, you'll be even more humiliated and hurt your feelings.
