Would you delete someone on facebook who ignores you while sending condolences to your brother/sister?

My cousins wife who acted like my friend in the past, we hung out, but don't anymore,
wrote on my brothers wall "sorry sweetie your in our prayers" about our grandmother dying. While she is ignoring me and has not wrote anything on my wall. Should I just delete her and forget her? In fact should I just delete everyone who does not say anything since they would not be my real friend anyway? Im tired of being Ignored.
And She's the one who applied to be my friend and I approved it.

It seems that they don't care as much about you as you do them. Don't worry about them anymore! People don't have as many friends as they think they do. If you have a couple good friends you are doing good!!!
