One word for the feeling of comfort talking to a friend [closed]

Question

I feel very comfortable and frank while sharing my personal stuff like issues/likes/dislikes/experiences to one of my friends. Being with that one friend is comfortable.

1. How do I describe this feeling in one word?
2. What word would be appropriate (except for comfortable and frank) if I were to tell that friend that:

   "I feel very ___________ talking to you!"

I wanted to express my this feeling to my friend.

Edit: So to be exact, my question is how should I put this in more better words:-

"I feel very comfortable with you!"

Answer 1

"Feel comfortable" is a good choice, "feel at ease' is an alternative expression you may use:

• relaxed and comfortable: The girl behind the bar was completely at ease, chatting with her customers as she mixed their drinks.

• I feel at ease talking to you....

Consider also the expression "to open up". You are more likely to open up with a friend:

• (about someone or something) (with someone) and open up (on someone or something) (with someone) to speak freely about someone or something; to speak a great deal about someone or something.

  • After a while, he began to open up about his disagreements. He opened up with us about the accident. She opened up on Fred with Alice.

Answer 2

Have you considered 'simpatico'? (MW, definition 2)

being on the same wavelength, congenial, sympathetic

It describes the relationship more than it does the person - someone who's simpatico for you may not be simpatico for me.

I find Nancy very simpatico; I feel like I can talk with her about anything.
