There are so many signs that could mean your partner is cheating, if you suspect your partner you should keep a close eye on them for a couple of weeks and make notes of their every move this way you will be able to tell if they have changed from their usual routine and opens the possibility that they are cheating on you.

The easiest way to do this is to hire a private investigator, however, this can be expensive and will also add to your guilt if your partner is not cheating. My advice is to start off by looking for these signs then if you feel it is necessary move onto the next step.

1) Is your partner more defensive than normal? Do they overreact when you ask simple questions, such as "what time will you be home" or "who did you have lunch with today"? If so this is usually a sign that they are feeling guilty about something. They often turn the question around a make you out to be the guilty person by saying things like "You always think I'm up to something, I'm sick of getting 20 questions when I come home, don't you trust me?" This type of behaviour is indicative of guilt. And your partner is probably cheating on you

2) Talking about someone too much. Has your partner started talking about a colleague or friend more than usual? This does not have to be in a positive way, it can include derogatory comments, and comparisons to you that are supposedly flattering. However, if a person talks about someone a lot it means that they are in their thoughts all the time, and this is when you should be suspicious of your partner cheating on you.

3) The Business Trip. This one is fairly obvious and it is easy to catch your partner out. Lets say they have suddenly told you that they need to go on a last minute business trip, however they have no details of where they will be staying, and no contact number. This is immediately suspicious, the first thing you need to do is call their work and talk to a colleague or superior to make sure they are going away. Otherwise chances are they are cheating on you!

I hope these three signs prove useful to you, just remember that whether or not your partner is cheating on you, the suspicion and guilt can ruin your relationship. You need to ensure that you are in a trusting relationship, if you can't trust your partner maybe you should not be with them.
