Think about the horse in all aspects too. If you are not in love with her, then don't take her. But also remember that she (the horse) has trust in you. If you don't fully love her, then don't put in the time. If you do love her, then take her. Responsibility can be a scary thing, but if it is something that feels right to you, something that you feel in your heart is what you desire, then go for it. Only you know if you truly want this horse for your own, or if you are taking her to "keep her from going somwhere bad" when you don't fully love her. If that is the case, then I think you can help them place her in a perfect, loving home where she will have an experienced handler like yourself. You can continue working with her until then, even if it takes a good year or longer. If you don't feel up to it, then don't do it. But if you do, then good luck and enjoy what is to come!
