Are You Dating A Serial Cheater? 9 Signs He’s Incapable Of Being Faithful

Serial cheaters also tend to be pathological liars. They have excuses for every behavior they exhibit that pretty much proves their infidelity and they’re seasoned experts when it comes to turning arguments around and placing the blame on you. It can be hard to spot a serial cheater, but there are some obvious signs you’re dating one, so pay attention.

  1. From what he’s told you, his exes are all crazy, jealous stalkers. A huge sign that someone is a serial cheater is that they’re on bad terms with all of their exes and their relationships clearly ended with a bang. Of course you don’t want to date a guy who’s best friends with his exes or always talks about how wonderful they are, but if all of his exes are crazy, jealous stalkers according to him, that’s definitely a red flag. Maybe they did act crazy at some point, but he probably gave them many reasons to do so.
  2. He doesn’t answer his phone in front of you. Sure, it’s polite to stay off your phone when you’re enjoying the company of someone you’re dating, especially in the beginning of the relationship, but it’s a warning sign if he never answers his phone when you’re around. If he turns his phone on silent when it rings or doesn’t answer texts even when his phone vibrates a few times, it’s probably not because his attention is all on you—he’s probably hiding something.
  3. He has a lot of girls that are “just his friends.” He gets Snaps, texts, and comments on Instagram from girls you don’t know or haven’t ever heard him mention and when you ask him who they are, he just shrugs and says they’re his friends. Of course they could be just friends, but more likely they’re women he’s keeping on the backburner or possibly girls he’s hooking up with on the side. Either way, this is definitely a sign of a serial cheater.
  4. He’s either unreachable or answers your texts immediately. Is he overly available to talk with you sometimes but at completely unreachable at other times? That’s a sign he’s a serial cheater. He might be busy at work or with other obligations at times, but if this happens regularly, it’s definitely a red flag. He may be unable to respond to you when he’s cheating and so he overcompensates for his lack of communication afterward, especially if he’s feeling guilty.
  5. He posts regularly on social media but never mentions or posts photos of you. He might post a Snapchat or Instagram story of the meal you’re eating or the view after your hike, but he doesn’t ever post any of the two of you. This is a sign he’s a serial cheater because he may be friends with other girls he’s secretly seeing on social media and wants to keep them in the dark about your relationship with him. He doesn’t have to constantly post about the two of you on his accounts, but if he never does, that’s definitely something to worry about.
  6. He accuses you of cheating or being disloyal to him. A lot of times, cheaters accuse their partners of being unfaithful to deflect from their own behavior. If he does this often, it may be a sign he’s a serial cheater or just very insecure. Either way, it’s frustrating, especially when you’re being a loyal girlfriend.
  7. He’s super defensive when you call him out on anything. Whenever you ask him why he has so many female friends or why he never answers his phone in front of you, he gets super defensive and even angry. He tries to make it seem like you’re the one who’s acting out of line and overreacting for even asking him about it.
  8. He’s overly complimentary and affectionate towards you. When he’s with you, he compliments you constantly and is super affectionate towards you. This might not be because he likes you—he might want to try and make it seem like it would be impossible for him to cheat on you. Serial cheaters have reasons for everything they do, and this is a sign that he is one.
  9. He tries to justify his actions immediately instead of just apologizing or changing his behavior. When something he does bothers you, instead of apologizing or working on changing that behavior, he immediately responds with why it’s OK and why it shouldn’t bother you. It almost seems at times that he’s already prepared these excuses in his mind because he’s so quick to answer with them. Not a good sign.
