<waves> I have seen a nonsexual love spell.
Maybe it doesn't count because I wrote it.
It was during a dark time when I was very depressed. I couldn't see the fact that people loved me. (ie, friends and family.) I'd also just broken up with a boyfriend of 4 years for virtually no reason, etc. After a friend basically gave me a stern wakeup call about this, I did a spell on myself to open my eyes and heart to the love I was already getting. I also asked the Universe to send some more my way, since over the course of this depression I'd lost friends. FYI, I'd also actively gone out and looked for friends and did some personal work in terms of being more friendly and more loving. It worked.
I'd also like to point out that it's *very* important to specify what you want when you do any kind of love spell.
For example, if you happen to be lonely and desperate, things can go, well, awry if you aren't careful.
I asked for love and companionship and comfort. Within a week I've met two different gents, both of whom are smitten. The first one I was strongly drawn to, but there were irreconsilable differences. The second started as a friendship, but soon escalated into love and sex. Over time this eroded into an extremely unhealthy relationship. Understanding fled over time, and we were both emotionally ill. I stuck with it for five years, and then gave up.
Then something interesting happens. Remember that guy who I had the differences with? Well, seven years later, we rediscover each other.
Then I discover that he's a stable, sane and reliable individual, and the problems I'd invisioned during the first few conversations he and I had were completely unfounded. Turns out he'd been in love with me for the ENTIRE seven years, patiently waiting for me to notice. Unlike the usual smitten guys, he was so polite and actually expected to "just be friends" and could accept that. (since being "just friends" is better than not knowing me at all, he said.) While I was visiting him, we were hanging out and I realised that it was "as true as it can be" love. I never expected to find someone I actually wanted to marry.
