You know his behavior isn’t kosher. Having friends of the opposite sex is normal for adults. Not wanting to sleep with every person you encounter is also perfectly normal. So either he’s projecting – he sees every woman as a potential liaison or his own sense of inadequacies is out of control.
The other behavior, ignoring you, giving you the silent treatment is manipulative and immature. He’s not behaving like an adult. He’s trying to punish you for his own insecurities; it’s controlling behavior. For many people this kind of behavior would be a deal breaker.
