Guys can share lots of stuff he won't ever share with you.
They gossip and support each other.
That's THEIR gift.
You have a whole set of potentials with him and what he gets from you might be totally different than what he gets from his male friends.
That's ok, right?
It is still with you he is engaged in a romantic relationship.
Now, if you feel you lack emotional intimacy with him, that's something you can develop consciously.
The first step is for him to feel secure in your presence.
It is hard to him to trust you if what you bring to the table are usally problems and challenging issues.
He needs to be able to relax with you, so give him comfort and nurture harmony at all times.
Once you achieve that, become a good listener.
Guys love sharing once they realize you actually enjoy hearing what he says.
The next step is to invite him to share more with follow up questions.
That's actually a coaching technique but it is definitely something you can ad to your conversation skills.
Say things like:
"Tell me more about that..."
"If I get you right, you are saying that..."
"So, what would you do if..."
These are all invitations to share.
Once he starts sharing, you need to be a good listener.
Creating emotional intimacy with your partner is a skill you can train.
It does ad a new dimension to your relationship.
What about his mates, how should you stand in that?
Well... Let him know that you are happy for him having these friends.
Be ok when he has a night out with them.
Be friendly with these guys when they come for a visit.
You REALLY don't need to compete with them.
Having them ads actually value to his life and expands your network as a couple.
It is a good thing he has them in his life.
To your power!
