Or you could look at it that the break-up is exactly what needs to happen at exactly the right timing. Maybe a month from now you can look back and see how this apparent "tragedy" was exactly what was needed to move the relationship in the the "right" direction, whatever that may be.
Also, as previously stated, internet spellcasters have a very suspect and poor reputation within the magic community. There are awesome for-hire spellcasters out there, but they are few and most inexperienced people would not be able to tell the real ones from the fakes. It is possible that you paid money to someone who did no spellwork for you and further lied to you about fake results.
Assuming that is not the case, that quality magic WAS done for you by a reputable worker, then i personally second-guess nothing when it comes to early results and early signs and omens. A break-up could be exactly what is necessary to get your results in the long run, or it could be the Universe being extermely merciful to you - telling you there's no chance at all for this relationship, therefore it's over. Only you can be the judge of that. Pay for a tarot reading from a reputable, experienced worker if you need more help reading the signs. It's easier to find a good over-the-phone card reader than internet spellcaster.
