Yes, if you cast a love spell with exact instructions they work. If you make mistake during a spell or before a spell then may not work. That is why I always suggest people must hire a professional spell caster. A spellcaster who is an expert and knows which spell is going to fit your situation. Sometimes you are casting spells that may not fit your situation. Also, in the worst situation, there may black magic involved in your situation. So, only do love spells work if you do in a proper manner and the spells with full details. Never cast a spell if it is not with full instruction.
