In my experience, the primary factor that generates love is the amount of time I think about positive qualities in a woman.
It's a fairly simple and surprising hack of my brain that could very well work for you too: if I devote enough time (say, a couple of minutes every hour) thinking about what I like in a woman, my brain will automatically start to generate feelings of love. On the converse, when I feel a lot of attraction, if I consciously stop thinking about her, the feelings intensity diminishes drastically.
It's almost like the brain was seeking to maintain internal consistency: if you think a lot about someone you're attracted to, it must be because you're in love, and viceversa. The best part is that, since we don't have access to our internal workings, the feelings generated in this way feels very true (they are true, actually).

My advice then is: before trying more invasive hack of your brain, just devote some time to regularly think about what you like in her. There's a good chance that soon you'll start idealizing her.
