I would like to see friendships, but I would like the player character to make friends (and enemies) based on her actions, not just on some unrelated string of dialogues where I get "rewarded" with friendship-points, or whatever, if I pick the right choice. I like it when companions and other npcs have their own motivations and agenda and is not just mindless puppets.
As for love.... of course it should exist in the game, but I hope there will be no romance for the player character. I have not yet played a game where it was done well (and that includes BG2 btw, I see people hold that up as a shining example of romance excellence and I don't agree at all). It always ends up forced and silly, especially in games where the player character doesn't have a pre-set personality. In a game where you can be anything from a friendly giant berserker to a small fuzzy-eared sociopath mage, it will not make sense at all when the same npc falls in love with them and says the exact same lines. At best it's unintentionally funny, and at worst it ruins otherwise intersting characters by forcing them into a type of role where they don't fit at all. Now, try to imagine writing dialogue for every possible combination of player character personality type and romance npc(s), add options for male/female and straight/gay to all that and you got a LOT of work for a tiny and optional part of the game, and in the end it may still just end up being kinda pointless and bland.
