Should i pursue her even though im not sure of my sexuality?

I think you should first pursue a friendship with her and then take it from there. In my opinion, I think it is unfair to date someone when you are unsure of your sexuality. Because you're them giving false hope that something could come out of it, and if you're only friends, no one gets hurt. However, it will be her choice to decide if she would like to pursue something romantic with you. You can always talk to her about your feelings and perhaps she could be help you.

I mean, I've always known that I liked women since I was really young. And being so young, I had no idea who to turn to, so I decided to come out to my friend (I made her guess ) and I discovered that she liked women as well. She and I did actually dated for a while, but we broke up and now, we're just really good friends.

 

I suggest you try to befriend her and maybe talk to her about these conflicting feelings you have. She might be able to help you out.
As far as the romantic feelings are concerned, if they insist after you befriend her there is nothing to lose by telling her. You should just make sure to let her know that you are unsure of your orientation.

 

Be friends first, then if it happens it happens. As long as you are totally honest with her, then there won't be a problem.
