When it comes to relationships, trust is everything. Without trust, you can’t build a healthy and long-lasting connection with someone.

If you’re currently seeing someone and you’re not quite sure whether you can trust them or not, here are 8 signs you’re dealing with an untrustworthy guy.

1. He lies to you

Lying is a serious red flag in any relationship. If your partner lies to you about small things, it’s only a matter of time before they start lying about more important issues.

If you catch your guy in a lie, address it directly and see how he responds. If he gets defensive or refuses to take responsibility for his actions, it’s a clear indication that he’s not trustworthy.

2. He’s secretive about his phone

While it’s healthy to have some privacy in a relationship, if your partner is overly secretive about his phone or his online activity, it could be a sign that he’s hiding something.

If he’s always protective of his phone and doesn’t let you use it, it’s a warning sign that he could be cheating or talking to someone behind your back.

3. He avoids meeting your friends and family

If your guy is hesitant to meet your friends and family or is always coming up with excuses not to attend events with you, it could mean that he’s not serious about your relationship.

It’s a red flag if he’s not willing to integrate you into his life and introduce you to the important people in his world.

4. He makes promises he can’t keep

If your guy is always making big promises but never following through on them, it’s a sign that he’s not trustworthy.

It’s easy to get swept up in the moment and make commitments, but if he continually fails to deliver, it will leave you feeling disappointed and let down.

5. He’s not consistent in his behavior

If your partner’s behavior is inconsistent and unstable, it’s frustrating and confusing. If he’s not acting in a consistent manner, it could be a sign that he’s not ready for a serious relationship.

If he’s hot and cold, it’s a sign that he’s not committed to you or doesn’t know what he wants.

6. He bad-mouths his exes

If your partner talks negatively about his exes, it’s a clear indication that he’s not over his past relationships.

It’s normal to have breakups, but if he’s still holding on to anger or resentment, it could mean that he’s not emotionally ready to invest in a new relationship.

7. He’s overly flirtatious with other women

While it’s natural to be attracted to other people, if your partner is constantly flirting with other women, it’s disrespectful and untrustworthy.

If he’s not able to control his impulses around other women, it’s a sign that he’s not fully invested in your relationship.

8. He doesn’t take responsibility for his mistakes

If your partner refuses to take responsibility for his mistakes or always blames others for his problems, it’s a sign that he’s not trustworthy.

It’s important for both partners to be accountable for their actions and work through problems together. If your guy is always blaming others, it’s a clear indication that he’s not mature enough for a serious relationship.
