Trying to be positive - with hope

[limbo]

Thank you all so much for the input, I have realized that h really has been with this ow now for almost 2 years on and off, and this really is something that I worry about.
He swears to me that there has been no further contact since he sent email telling her he wanted to end it, but you know it just doesn't make sense to me, I just don't buy she would have no contact with him, trying to get him back.
I also feel like there is to many questions about his return, 2 weeks ago, he tells me he can't stay, and he doesn't want to stay.
However he goes for a walk(he also says he didn't contact her)and comes back and says he wants to stay.
I think what worries or bothers me, is that he can seem to change like the wind, while we were away, D15 and I had a huge fight, and basically I just broke down, and say no one wants me, he told me he did, and that he loved me, a week later he is telling me he wants to leave!
How can I trust his feelings when they can change like this!
