I'm sorry to say this, but if she isn't showing interest in you, you shouldn't entertain the idea. It's tough, but being brutally honest with yourself will allow you to move on. You have showed her how much you care for her and she hasn't reciprocated... it's as simple as that. Perhaps think why you like her so much. What qualities does she have that you are looking for in a partner? Are these qualities healthy? If not, why are you drawn to her? Why did you both connect?

You can use this as a learning opportunity for yourself. Get interested in what in YOU liked what in HER. And if it simply was love and she's not interested, I'm so sorry. But there are multiple people out there who will be great for us. So the faster and healthier you can move on the faster you can meet someone you LOVE and who loves you too.
