It's such a fine balance, cultivating a friendship. On the one hand you have to just "let things happen naturally" eg not getting involved in too much too soon, then again the advice in the book upthread says contact time/ shared interests are important.
INeedNewShoes I think I've fallen foul of what you describe
A person I felt a nice friendship was growing, has become strangely cold towards me when we meet up at our shared interest group. Maybe I just tried too hard although I hadn't demanded we meet up loads, but maybe in my effort to show warmth and concern, to engage (as I feel good friends should) she has decided she wants to place distance between us. I have backed off and given space, as it's easier than facing rejection. I'm thinking she may have felt I was trying to get too close. The balance is so difficult to get right (like any relationship I guess)
Tantric, I think you're right, friendships are often overrated - nowadays esp social media, puts pressure on to have friends. True friendship is very difficult to get right, so both people get what they need from it.
IMO reliability (being there, not crying off arrangements) loyalty (not talking about people behind their back)and consideration (two way dialogue not me me me) are values for good friendship but often lacking
