I've kept Lydia as my follower. I am a level 40 Nord and am Archmage of the College. I started working my way up in the Companions and hit a major glitch. In the Proving Honor main quest I was accompanied to Dustman's Cairn by a Companion. I thought Lydia would come too as I've been on a number of dungeon quests where a NPC fought along with Lydia and me. No Lydia at the Cairn and when I returned to Jorrvaskr after the quest, she had disappeared. Using the console lhelp I get Lydia's ID (000A2C8E) and did a placeatme to get her back. The original Lydia showed up - no ebony armor or fancy blade. I rearmored and armed her and started the next Companion main quest -the Silver Hand. This time I told Lydia to wait for me in Jorrvaskr hall. As a preface to the quest (SPOILER) you are initiated into the main circle and become a werewolf. Lydia now tried to kill me and then ran off saying I never should have done that. Again, no Lydia. I can do another placeatme, but this is nonsense. Whats happening here? Is this normal? Am I going to have to give up completing the Companions quests?
