Bro if you're sincere in your love for her, keep praying and make istikhara.
Whatever you do, don't lose hope, but you cant pray and think to yourself "omg thinks are never going to work out

"
You have to be hopeful and sure that Allah listens to you, and don't expect quick results.
Give her some space, and be a gentlemen towards her but don't be too keen.
You need to let her have her space for now, and dont cry and hang up on the phone.
Don't do anything irrational, although its hard sometimes to control your tears and emotions, especially when you're deeply in love with someone.
Only supplication can change fate iA. Make a promise to Allah that you will stop doing a certain sin (e.g. not waking up for fajr) and stick to your word and goal.
the Prophet (SAW) said :
“Righteous deeds increase one’s lifespan. Supplication affect what is predestined. A man loses what he has (or can gain), due to sins.”
Ibn Majah and Ahmad
Salman related that the Prophet (SAW) said,
“Destiny can only be deterred by supplication.”
Concerning this the Prophet (SAW) said,
“Whoever invokes Allah to have something, Allah will surely give him what he asks for, or will remove some evil which is impending unless he asks for the committing of a sin or to severe the ties of kinship”.
Muslim
