RONSO, the second time around is the hardest for re-recruiting. All of the Houses know that you went with xyz and left.
They may not know the real reasons that you left so wont recruit you.
Give it a little time and get to know members of other Houses.
Do your checking of what the Nationals Stand for, what other Chapters who are close are like.
It is hard to beleive that you would look back to the same house that you were in. Of course it depends on why you left. If they ignored you then I would have second thoughts.
You were not just trash to be set out curbside and forgotten.
Good Luck!
