My heart goes out to you mari.
I have spoken with people who share similar relationships such as yours, and from what I have gathered they are difficult at best to maintain. Everyone involved must be open, honest and above all respectful. Communication between all parties is a definate must.
Even then life can throw a curve ball into the mix: there are times when a person's perceptions, feelings, values and ideas change. They begin to question themselves and feel vunerable to everything. Sometimes, it takes awhile before another person will open up and communicate thier own worries and fears as well.
I am sure that all three of you will be able to sit down together and work out this problem.
Judging in my own opinion on how your Master feels about you, I do not think that he would not just tell you to leave without resolving things first.
I am sorry that this has happened to you, I don't give the greatest of advice, but I hope that I helped out a bit.
