I proposed, she is thinking of moving w/ her X (i am not supposed to know) but she kept the ring, what do I do

We had some rough weeks, but I feel that she is perfect for me, she had already answered yes in the past. I know that I did not ask at the right time (when I was moving stuff out) but I felt that I had to, we spent the next day talking and the day after together like a new couple. I never did hear an answer, all she said was that she wanted some time alone to work on her then we could work out things together. Then the following day she is looking online for a house where her Ex lives (she has a child by him). He is worthless IMO and she has always felt the same but she loves her child more than anything and I know that she wants her child to spend time with his father so I am afraid she is making a bad mistake, she cut off communication aside from one call to check on me yesterday, what do I do? I love her more than anything, this is a much more complicated issue than I can type in here but know that she was madly in love with me till the weeks that we fought, and they were petty.
