Getting my life back after my last breakup

I watched porn while I was dating her and we dated a for a few years. I think it led to us breaking up since I kept wanting more and more from her. It has been more than 7 months and I still think about her all the time and I dislike that part of me. I usually watch porn every day and a bit during my days off. I want to focus on other things in life and not let this hold me back. I'm nineteen in college and want to bike the tour divide in 2018. I don't want to use fapping as an excuse for myself anymore.
