So my guy and I were never in a relationship. We just dated for a little but were never "official" (it lasted for a couple months). 

I just want to manifest him back and see where it goes. I'm thinking relationship, but it definitely doesn't have to lead to marriage or anything.

A lot of these LOA principles involve sending out "love" to them. As Cherished once said "pure unconditional love". But I'm not in love with him. Maybe one day I will be, but I'm perfectly fine with "seeing what happens". 

So should I really be sending him love? Am I just sending out love in general (the kind you can give out to anyone because you're a nice person but it's not relationship-specific)? Or is "love" just the label we're putting on positive energy that we want to emit to the person we're trying to manifest?

I certainly like this guy and want to see what happens, but I don't love him. Maybe one day.
