Hi Mj, First things first, I am just 17 and have a very little idea about what a relationship means. But I am a boyfriend who confessed about my addiction on day 7 of our relationship. True she hated me for some minutes but then as I explained her about how it works the same way as any other addiction and my fight against pmo on nofap she had her trust back on me. So many factors actually worked in my case like I didn't lie and told her truth as soon as I can and secondly I explained her how I mistakenly went inside that shitty addiction during my early teens. So I know you lied her much (it's ok now) ask her to give you just one last chance (you literally need to beg). The letter seems lengthy. Try to meet her that would make a big impact as it would show that you really care. Last but not least, remember what you said and keep all the promises you make to her. Good luck and remember a girl can never be the only reason to live. Make her a part of your life and not your life.
