Simple most of it happens unexpectantly and naturally-> Form bonds of trust with people such as a friend-> listen to your natural sense of attraction when you feel you're starting to like or become attracted to someone and they start giving you signs back -> take risks and go on that date if they ask you out or ask yourself, the worst they can say is no, if that's the case you can still be friends or try again with someone else. When you're hitting it off and falling for someone trust me, you'll feel it. Do what it tells you too even if it can be a little scary.
You don't look for it. Have it look for you. It'll show up when you least expect it.
I was never looking to fall in love with anyone, yet 2 years ago, I met one boy on here that just happened to share the same interests as I did and we hit it off really well for a few months before he asked me out. And since then, we're still together. c:
