 Has your partner been acting strange lately? Do you suspect they're seeing someone behind your back? Changes in your partner's behavior may feel subtle, but could be red flags that tell you something's wrong. Here are 10 signs your partner might be cheating on you. Before we get into it, I'd just like to say hello to everybody and a big thank you to Psych2Go for letting me be a guest in this video. You might recognize my voice from other videos such as 9 signs you're secretly a cat and 8 signs you're actually in love. Thanks Psych2Go. Let's get into it. Number 1. They're obsessed with their looks. Has your partner been more interested in their beauty lately? Suddenly, they're hitting the gym more than usual and making a point to show off their looks on social media. Sure, they might be doing it for themselves, but it also might not be just for you. Loving the gym doesn't make somebody unfaithful, but if someone's cheating on you, chances are they're pumping iron. Number 2. They're no longer interested in sex with you. While it's natural for many couples to have less sex as their relationship progresses, it can be a red flag when they're suddenly not interested in having sex with you at all. Although there can be many reasons to refuse sex, it's good to talk to them if they constantly postpone or turn you down without a reason. Number 3. They're more attentive to you than normal. Just as it can be a sign when your partner is suddenly not interested in sex, it can also be a warning if they suddenly show you too much affection. They might give you constant displays of affection and may even want to have sex with you more times in a day than you can take. They may smother you with love to cover up the guilt they feel for their betrayal. Number 4. They always talk badly about another person. You could take this at face value, they might just not like the person. But there's room for judgment here. Is your partner always complaining about a co-worker or friend? Telling you how gross and unattractive they are when they really aren't. They might be trying to cover up their secret that the person they keep talking about is a secret lover. Number 5. They are constantly arguing with you. Has your partner been picking fights with you? Are they always upset at you for some reason? They might be unhappy in their relationship and are comparing you to their new secret lover. Some cheating partners may even threaten to break up in the middle of arguments. This might feel cruel and controlling, but what they want is for you to agree and end the relationship, solving the problem they've created. Number 6. They have low self-esteem. Does your partner need constant validation? Partners with low self-esteem may seek or respond to validation from strangers when it's about their looks and desirability. Strangers at bars or online and easily woo these bloody people. If you don't tell them every day that they are your world, they'll find somebody else that does. Number 7. They're defensive with their phone. Of course, we're all entitled to our privacy. Being in a relationship with someone does not grant you free access to their phone or social media accounts. But if your partner works really hard to ensure you don't see who or what they text or get snappy with you when you just glance at their screen, there might be something they're hiding from you. Number 8. They get texts at odd hours from strangers. Does their phone light up with messages from unlisted numbers and people you've never heard of? It can be a sign if your partner is suddenly getting texts from strangers at odd hours of the night, especially if it's accompanied by their change in mood or behavior. In this case, they might have some explaining to do. Number 9. They project their behavior onto you. As your partner accused you of cheating out of the blue, even though you've never done it, projecting is a defense mechanism where you attach things you don't like about yourself onto other people. People who cheat may project their behavior on you by accusing you of cheating. They might bring it up as a serious accusation or even as a repeated joke. Number 10. Your intuition's telling you something is wrong. Does it feel like something's wrong in your relationship? Sometimes, you just have to trust your gut. When your partner's overall attitude and the feeling you get from your relationship changes, there's no one better than you to know when something's up. Remember, you can't accuse them of cheating without proof, but it's always a good idea to have a discussion with them first. Of course, everyone's a little guilty of these behaviors at one time or another, but it's all about what feels out of place for us and what seems excessive.
