Good Afternoon,
Your first post was this morning asking for help with your girlfriend and now you have given up on her. Did something trigger you or change ?
I am sorry this has happened to both of you. I hate to think that everyone unfortunate enough to have such a painful, difficult illness must face a life of loneliness because the prevailing advice to any potential partner is "Run! Save yourself!"
However, you sound young and if you are not able to commit now then you have chosen what is right for you so let her go and do not worry about what her family thinks. Do you still respect yourself for being honest and up front on how you feel ?
I would suggest you take a break, catch you breath and move on with your life.
Kindly,
Kitt
