Is your date cheating on you? If the answer is yes, there will be obvious signs. Your date will become less talkative, may be defensive at odd times or may just be acting strange when you are together. If you feel you are being cheated on, be proactive; talk about it. Let your partner know that you won`t tolerate their cheating; make them choose between you and the other person. If they won't, cut the relationship off completely. You deserve better.
