Need advice on what's my next step with this girl?

hey it sounds like you really like her and it sounds like you get along quite well which is always good :D how old are you might I ask? i'd say ask her in person if you can take her on a date or ask her to hang out with you just you two so your hinting to her that you would like to get to know more about her and it will show your interested in her aswell. Just see how it goes you have nothing to lose she can either say yes or no, if she says no then just carry on being friends with her if you enjoy her company or try and persuade her and say that we can just hang out as friends then, that will show you respect her decision to not make it a date but you never know when she spends time with you as 'friends' she might think perhaps she likes you more that just hanging as friends, but dont get your hopes up thats all it's like with all decisions that your unsure about it's taking a risk and going into the unknown but if you never take that risk you will never know what her answer would be and nothing may never develop between you two romantically, it's up to you but im just giving my opinion i hope that I helped you :) and i hope it goes well !

Go ahead and contact her on POF and tell her you're going to be at the Meet and would like to partner up running along with her. Then at the meet ask her out on a date maybe even for that night.
