I guess I'll just sulk for a while and then tell the second friend.

The first friend, it's been a while, I'll just let it go - if she ever invites to stay with her, I'll say no thanks and 'you yelled at me'. She would like to be invited to our place, but honestly, don't know where to put her since the attic has been a mess, and I'm not that keen on her visiting anymore.

I'll still consider them friends but will try to meet other people too and not rely on them that much.
I feel like I have been too giving (with stuff and supportive/positive attention or communication, and they haven't really reciprocated that well). So I'll just stop being so giving and supportive, and see what happens? (Easier said than done, as I've read so many books on supportive/positive communication and listening yikes! I listen too 'well' and people felt they could 'unload' on me.
I don't know whether to just say I'm busy or someone is calling me to do something - works best with this friend, or just limit calls and not answer.) Ideally we'd have a constructive conversation about it, not sure if it's possible?
