This shows that he or she only loves you, and you are the only one in his heart! If you don't accept him (her), then he (she) will not fall in love with others again. Only by staying away from home and avoiding the helplessness and sadness without you will he die alone. Choose if you like, and don't let the other person suffer any more. Isn't it lucky to have someone who loves you? May you grow old together!
