Why do Ethiopians NOT want to see Eritrea Succeed?

A very controversial topic. That must be RESPECTFULLY handled.

But it must be addressed. It has come to my attention that through many Eritrean websites, forums, or anything to do with Eritrea really many Ethiopians feel a certain way with the topic of Eritrea. Me being Eritrean always made me wonder why is their so much hate and animosity toward any Eritrean progress. To be fair i have seen a lot of Eritrean hate on many Ethiopian forums but its not to the degree of hate from Ethiopians.
