The key is not so much about deep friendships, it is about interaction with the opposite sex.
So, you don't have to build a strong friendship with a male friend.
All you have to do is even though you are in a relationship, you still keep interacting with other men:
- Flirt a bit.
- Chat with a guy you just met.
- Activate your social power when attending an event.
Once you realize that other men like you too, your level of power and confidence is REALLY boosted.
When you rely only on your boyfriend or husband for male validation, this makes you very dependent on him.
The moment he transfers a bit of his attention to another woman, even if it is for a couple of hours and there is for sure nothing going on, you still feel insecure and left out because he is all you have.
Now, if the moment he comes back home, he sees you on facebook chatting with an old male friend who just found you back, the balance is shifted instantly!
Let's get this right, ok?
The goal here is not to make him jealous. The goal is to have other sources of social validation in your life, not just your partner.
That's the key!
