Is master's bed also your bed? When you say "alone" I presume you're meaning alone with him.
As I say I can only give you a logical perspective having had very little experience in all of this. But if you have had childhood issues and you feel like that is still where your head is I can't really see how making you leave your bed or really even your masters bed for another woman could prepare you for anything except to maybe re-visit a lot of childhood pain unnecessarily.
Would you do that to an insecure child? Hell no? You would let the child be present and and see first hand that the parent/master can and still have love for both.
Just my 2 cents but I think you've seen this work badly now you should be making sure that it works the way you need it to. Since exploring polyamory I have believed that it requires high levels of emotional maturity to work successfully so I'll be following your journey will interest.
