Hey ladies i need your help asap and possibly guys if you have any input feel free to help a brother out!! My girlfriend is currently upset at me so much beyond comprehension because my lack of financial stability that she tells me she does not trust me when it comes to finances. She even went ahead to say she loves me but does not know if she wants to be with me because of it which i dont blame her but i love her so much and shes got my heart and im changing things and she kind of feels its too late. She stated she wants to get married which i do as well but financially im not QUITE (ive got some dings on my credit report) of which im already working on that. Question is what do i do to show her that i can be the man she needs and i am capable of taking care of her eventhough she's well capable of taking care of herself. And how do i show her that i can change and have changed!! HELP I REALLY NEED IT!! Thanks guys
