I know it was 2 yrs ago but agree mostly with @rawkgalore. I think the narrorator is talking about a sort of possessive love this man feels for his new neighbor. I think he is not necessarily stalking her but she caught his eye. Watching her he sees the same loneliness in her that he has and he wants her to be with him.

He wants her but she's is not open to love probably because of her past love experiences. He wants to cure her loneliness with his presence but she's just not ready or is unaware of how he feels. So he makes a plan to "not-so-accidentally" run into her with the hopes of conversation and more. He just wants her to fall for him cause even from a distance he's already in love with her.
