If you stop looking for a relationship, life will literally throw one in your face. But there's like a ton of places you can meet people gym, running club, work, zoo. Don't be afraid to go places yourself, smile at people and you'll be surprised at how many react. I met my first girlfriend in McDonald's, I was ordering food and she complimented my accent. (I have a thick Irish accent)

Advice, you might not like it. But tell the women, you never saw her as a potential friend. That attraction will always be there the more you hangout etc. I hate to say it but cutting yourself off from her completely could be best for your mindset. Unfortunately it sounds like you need to wait a bit longer before you meet a women as attracted to you as you are to her
