You have your suspicions that something is wrong with him, but still no evidence. He may be a traitor, but there are also chances he may not, so it should be well thought out. Until you have proven nothing, take your eyes off his body language. You will understand more from what you expect.
1. He deals with himself many times more than before.
If you have noticed that you spend time fixing your hair, beard or taking care to look beautiful all the time, beware! This is a sign that your friend is cheating on you.
2. Do not pet after sex
If after making love he does not take the trouble to pet you, it could be an indication that there is someone else behind whom he is emotionally attached. He feels for her and is maintaining that kind of intimacy for her. Speak openly and express your doubts.
3. He always hides the palms of his hands
When people show the palm of their hand it means they are really with you. If he always puts them in his pocket or under the table (instinctively), be vigilant. I'm hiding something from you!
4. Covers the mouth whenever betrayal is discussed
How did you react when you asked him if he betrayed you or not? What move did he make? If you close your mouth with your hand it means that he is hiding something from you. Or is he a traitor!
5. Never leave the phone out of place
There are passwords everywhere and it is not a question of you having his cell phone in your hand without him being present. Why should he do this if he is not hiding anything? Call to mind!
