Don't waste your time wondering about how your man feels in your relationship.

At the top of nearly every survey about what singles want in a partner is a person who is faithful, loyal, and trustworthy. In other words, singles in a committed relationship want someone who will not cheat on them.

Unfortunately, the reality of that desire often comes to a painful end as time goes on. Accurate statistics are hard to come by (because lots of people don’t want to admit to cheating ), but researchers agree that 30 to 50 percent of men and 20 to 40 percent of women are unfaithful .

Can you ever know for sure that your partner won’t cheat? No, because people and circumstances change over time. But you can look for specific personal qualities that offer a strong predisposition for faithfulness instead of unfaithful ness. Here's how to know if a guy won't cheat on you.

1. He keeps his word in other areas.

Reliability and trustworthiness across many aspects of life is a good indicator of faithfulness in your relationship.

2. He likes your friends but keeps a respectful distance.

Researchers found that nearly half (45 percent) of men and more than one-fourth (26 percent) of women are attracted to friends of their partners and are tempted to act on it.

3. He is realistic, knowing no one is immune.

One of the biggest dangers is thinking “it could never happen to me.” Approximately 69 percent of people who cheated never considered it a possibility before it happened.

4. He is aware of the danger zones.

For instance, business trips are particularly troublesome: Thirty-six percent of men and 13 percent of women said they gave into temptation on a business trip .

5. He has a strong emphasis on “we,” not “I.”

Faithful partners recognize the value of preserving the relationship’s love and intimacy — and will take measures to protect the special bond they share.

6. He is invested in maintaining a friendship, as well as a romance, with you.

Many individuals who get involved in affairs have been unable to deepen their love relationship beyond the early phase of infatuation and adrenaline rushes.

7. He maintains proper boundaries with co-workers.

That’s because 60 percent of affairs start at work . And keeping a strictly professional relationship with co-workers is how to know if a guy won't cheat on you.

9. He is not a narcissist.

People with narcissistic tendencies — self-absorbed, lacking empathy — are especially prone to straying .

10. He knows the importance of a satisfying sex life.

After all, 52 percent of people with unsatisfying sex lives said they would be tempted to cheat, while only 17 percent who were sexually satisfied said they would be tempted.

11. He doesn’t have an excessive need to be admired and liked.

A need to have one’s ego boosted leads to inappropriate relationships from someone eager to flatter.

12. At the appropriate time, he will be completely open about finances.

Since money disputes are the number one cause of divorce , psychologists have coined the term “financial infidelity,” in which individuals deceive their partner with hidden debt, secret credit cards, and undisclosed shopping sprees.

13. He doesn’t flirt with anyone but you.

Flirting or checking out other people is disrespectful to you, and disrespect is a step toward unfaithfulness.

14. He does not keep secrets.

Small secrets can blossom into big ones down the line.

15. He has extinguished old flames.

Many people look back on past relationships with fond memories, and some even maintain friendships with past loves. But wise individuals guard against too much interaction with an ex. That’s because 32 percent of women and 21 percent of men who admitted to acting on sexual temptation said it was with a former boyfriend/girlfriend.

Manchester United risk losing up to 10 players if Jose Mourinho survives for the rest of the season, SportsMail reports.

The 3-2 comeback win over Newcastle on Saturday has raised hopes that Mourinho can turn a corner and keep his job at Old Trafford.

However, there is another school of thought, that the victory only papered over cracks and there are still tensions inside the dressing room.

Up to 10 players might consider their future elsewhere, if the Portuguese is not fired.

There are: Paul Pogba, Luke Shaw, Anthony Martial, David de Gea, Eric Bailly, Antonio Valencia, Juan Mata, Ashley Young, Phil Jones and Ander Herrera.

Paul Pogba remains the biggest concern, with the United’s £89million record signing desperate to leave the club and join Barcelona as early as January despite being told he is not for sale.

The Frenchman has fallen out with Mourinho and been stripped of the vice-captaincy, although Pogba could still push for a move to Spain even if the manager is axed.

Luke Shaw is out of contract at the end of the season and it is understood the England defender has no intention of signing a new one if Mourinho remains in charge.

Anthony Martial’s willingness to discuss a new contract in recent weeks is thought to be on the basis that he believes the Portuguese coach will not be at United much longer.
