When you’re in a relationship, you have a responsibility to continue to take care of yourself, and feeling confident and sexy is part of that. That is your responsibility, not your partner’s. Yes, that person may love you, but remember: love is a choice. Your partner is choosing to love you, but that doesn’t mean they find you just as attractive as they did at first. You should not stop doing everything you were doing to take care of yourself when you got into the relationship. You should actually be doing more.
