@ Rainbow i think it depends on the spell actually. if you cast a spell to make (person) fall in love with you, then yes. if you cast a spell to bring love into your life, no. this spell, you're asking the universe to bring someone new into your life, not a certain person. so you're not casting over them, you're asking for something. but if someone doesn't feel right casting love spells, whatever, their choice. i do agree though, casting over another to make them love you is pointless.
try something small like a candle spell or a honey jar spell. they will both attract love to you without casting on one person. to keep the person, i'd suggest talking with them about it, but a binding would work. maybe look into a handfasting ceremony though. it's a commitment ceremony much like a wedding, so i wouldn't advise rushing into it. you bind your and your love together. this won't ensure you'll stay in love though, it will just keep you together. like marriage it can be undone.
