Nobody would like to get cheated on, right?  These things will help you in tracking if something infidel is occurring between you and your partner.

Non-stop nagging: When she pinpoints every tiny imperfection on the relationship and keeps nagging about it continuously, and tries to stretch it as grounds for the breakup.

Asking your day to day routine: This question is validated for the workers who do not work from their homes, but inquiring this to a home based worker would be senseless. Your girl asks you routine as she might be planning a secret take home while you are out.

When she seems to be preoccupied with her thoughts: When you try conversing her and you observe that she is lost somewhere away from the world may be a hint that she is thinking of ways to break the relationship.

Doesn’t seem to answer properly in a confrontation: When you throw questions on her regarding the possibility of cheating, and she insists on keeping silence then you must start thinking about balancing your relationship as any time she may ask you for the breakup.

Common one- hiding cell phone from you: She hides her cell phone from you; that is just because of this apparent reason, and that is she doesn’t want her romantic messages to get addressed to you anymore.

Not interested in romance anymore: 

When she stops hugging you or getting close to you, then probably ‘you-are-being-cheated-on.’ She’s not into you anymore.
