Formal:
* J'aime parler à mon ami(e). (I like to talk to my friend.) This is the most direct and neutral way to say it.
Informal:
* J'aime bien discuter avec mon pote. (I like to chat with my friend.) "Pote" is a more casual word for friend.
* J'adore papoter avec mon copain/ma copine. (I love to gossip with my friend.) "Papoter" is a playful word for chatting or gossiping.
More specific:
* J'aime bien me confier à mon ami(e). (I like to confide in my friend.)
* J'aime bien rigoler avec mon ami(e). (I like to laugh with my friend.)
Important note: You would use "ami(e)" (male friend/female friend) in place of "pote," "copain/copine," or other informal terms.
Choose the phrase that best fits your situation and your relationship with your friend.
