1. See whether she denies physical touch.
Obviously, fundamental signs that something is wrong in a relationship is if one partner becomes uncomfortable being physically close to another. Whether it’s holding hands, cuddling, making out, or having s3x, being physically touch demands a great agreement of trust from both partners.
If one partner knows that the trust has been broken, physical touch can suddenly start to seem quite awkward and unnatural. If your girlfriend suddenly recoil at the thought of touching you, something’s up.
2. Let’s check whether she hides her phone from you.
If your girlfriend has secret relationship with someone else, there’s a good opportunity that her phone was also used to stay up-to-speed with him. Draw attention to the way your girlfriend handles her phone — does she keep it close to herself when she’s texting? Has she recently added a password? Does she refuse to let you use it? Does she seem reluctant to let it out of her sight? If so, she may have something to hide.
3. She suddenly becomes busy.
If your girlfriend suddenly becomes too busy to hang out with you for long periods of time, it means that she’s spending her free time with someone else.
4. She avoids your eye contact.
Being able to look someone in the eye is considered as a sign of sincerity and honesty. When people know they’re or hiding something from someone who’s close to them, it can become difficult or almost even painful to look the other person in the eye. If your girlfriend suddenly can’t seem to meet your gaze, something may be very wrong.
5. Know if she’s ignoring you.
The thought of getting the “cold shoulder” is enough to make any concerned boyfriend shiver. If you’re suspicious of your girlfriend’s true intentions, pay attention to the way she treats you when you hang out — does she seem indifferent or disinterested in what you have to say?
