The abuse had rhetoric in this thread is profoundly mentally ill. Why are men so eager to dehumanize everyone they hear about?
The dude probably was well intended and felt pity for her, but as the deal went on realized he really can't do it, can't imagine being with her for real, and withdrew. Nowhere is it mention that he treated her badly while still there. As unfortunate as all of this is, and maybe not 100% upright, there is absolutely zero "abuse" involved in all of that. Humans are allowed to leave relationships they do not like.
