Relapsed from almisse all my habits

Before I got a girlfriend, I had developed a lot of good habits, I was taking cold showers, I was meditating every day, I was practicing a skill for 45 minutes every day and I was doing nofap and was on a 30 day streak and started nofap 50 days before that. But when I got a girlfriend it was hard not to fap, and I started doing it again and since that I couldn't keep a streak for more than 7 days. I also lost all my other habits. I don't know if anyone can help me, but I am still working to get all my habits back.

EDIT: she also broke up with me because she thinks that I have changed a lot since we came together :/
