Alright man
The concerns i have for you are as follows:
1) Later on she told me that she dates guys but later gets bored of them after 2 weeks, typically.
2)She told me through texts that she likes me but wasn't sure
3)Which TO ME, sounds like I'm not entirely convinced.
So let me break it down.
1) She is not in to commitment, which could mean that even if you get her as your girl how long will you have her? Do you just want her to be yours for 2 weeks?
2) The whole "i like you, but i am not sure" thing is just BS. You say that there is the attraction there, right? If its there she is in to you. Thats good for you

3) That is a bad mind set to have. YOUR THE PRIZE. so by you saying i am not convinced that i have a chance is like saying i am not worth her time and attention. Which you are worth her time and attention. the real question should be is she worth YOUR time and attention?
Things you could do:
So like you said she gets bored easily(which is usually commitment issues) so to by pass her issues with commitment you could have her as a Fuck Buddy(FB). So this way she will not be worried about commitments and just have fun with you, while you fuck her brains out, and that will last longer than two weeks. And to get her as your FB is much more simple than keeping her as your girl. The attraction to you is there for her, monopolize on that. She even said that she "likes you" but she wasn't sure if she wants to date you and thats because like she said she gets bored easily. So make her your FB, This will put no commitment feeling towards her and you can still be light and playful with her and dont have to talk about emotions. She's not sure she could date you because she is not sure she could handle possibly hurting you(SHE LIKES YOU) With FB she cant hurt you and she will feel like she wont hurt you and she will be relaxed. You as well need to be more confident, you need to think that you are convinced she like you, because she does.
If you have any questions about what i just said let me know.
Hope this helps
