If introverts can say that "low-maintenance" friendships are great we can say the same about "high-maintenance" friendships!

I've always felt that a friendship works best when both people are equally invested in the relationship!

I,e, both parties initiate conversations/hang out and no one feels like they're making more of an effort than their friend.

One-sided friendships should never be acceptable.

Communication is just as important for a friendship as it is for a romantic relationship!

Both relationships are a two-way street and require both parties to be involved for them to work.

If it's not okay for you to contact/spend time with your romantic partner for 2 months it shouldn't be okay for your friend to do that too (Unless they're going through something but they should have the decency to tell you.)

Regular communication and hangouts keep the friendship alive and also ensure that both parties are present in each other's lives it also deepens the bond you have with your friend.

Is there anything else I'm missing?
