You can do a love spell at any point. In the middle of a relationship if you want. Quite a few people do it.
A reconciliation spell, as I understand them, is to bring the other person back. They'll return in the same state as before. So you would want to cast a love spell before then or at least some way of sweetening him up.
The only reason to cast a breakup one before reconciliation is if he's in another relationship already or you feel one is imminent. In your case, I don't think a break up one is necessary.
Hope that helps clarify things a bit.
