Four signs your partner is cheating on you, according to private investigator

The sad fact of getting into relationships is that some of them could result in cheating.

Right now, there are couples out there were one half is blissfully unaware that the other is doing the do with someone else.

There are also couples where one half is un-blissfully suspicious because the relationship feels different, but they might not be sure why.

Private investigator Aaron Bond told The Sun that there were four main signals to watch out for in a suspected cheating partner.

Pretty much all of them have to do with a change in behaviour, but it's how they change that you need to keep an eye on.

You shall not pass(word)

Some people think one of the ultimate demonstrations of trust in a relationship is handing your partner your unlocked phone since they could do anything with it.

If you were cheating, you'd be pretty f**king daft to hand over the evidence, and if you're being cheated on, you might see your partner's relationship with their phone change.

Bond said the things to look out for were 'changing their passwords' and 'taking their phone everywhere with them' so you won't be able to spot what's going on with their screen.

Putting the phone face down when you're around might also be something to think about, as it could mean they don't want you to see what messages they're getting.

Closing up like a clam

People in relationships are going to vent to each other from time to time, and if you're just getting into one, expect to hear a lot about how their day went and what's going on in their life.

However, if they suddenly stop doing this, it could be a sign you need to worry about.

They might just be in a funk or something else might have been happening, but Bond suggested it could be a sign that they're feeling guilty or even attempting to speak as little as possible to try and avoid being caught in a lie.

Livin' libido loca

It's pretty normal for the sex life of you and your partner to fluctuate with the times, and, according to Bond, when cheating occurs the amount of sex you're having is likely to go down.

On the other hand, he noted that in some cases 'they may also have more sex at home' as they're feeling guilty and might try to hide the cheating with sex.

Bond suggested that a cheating partner might try to 'introduce new things into your sex life that weren't there before' too.

Negative energy

If someone is cheating on their partner then they're in the wrong, but they might start trying to portray their other half as getting things wrong in an attempt to justify their behaviour.

Bond suggested that a cheater might start trying to find fault with you and your relationship to make themselves feel less bad about cheating.

Naturally, your partner cheating is not your fault at all, but you might be made to feel as though you're doing something wrong in the relationship.
