i am in a bit of a situation myself. celibacy is looked down upon in islam, that's why it's important that we get married and lower our gazes. if we cannot yet do that, we are required to fast to kill the appetites of the flesh. i also believe that we also have to be willing to accept what Allah swt wills for us, to understand al qadr. you are worried about trying to impress some wali. that maybe the root of the problem for you. you shouldn't try to impress the wali because trying to impress seems to appear that you are not being your true self. it is important to be your true self in this situation. it is also important for her to be her true self. since we don't date in islam we are dependent on one's honesty. honesty or the lack of it will be what can keep your relationship strong or be what tears it apart.
i know that we can all take the easy way out and do things unislamically and get what we want, but do we want to go against the will of Allah swt? are we willing to miss out on jannah, just to cool our flesh?
take it easy brother, if she is not for she is not for you, maybe the next will be for you. but remember, we also have to prepare ourselves to the possibility that it may not be the will of Allah.
