please help.

maddie
my boyfriend and I have only been dating for around 5 months. He has a short temper and gets mad very easily. although it gets difficult sometimes, I still stick with him and help him get through it. I really care about us and I know he does as well. I recently got an app called Happify. it helps you focus on the positive while helping reduce stress. I thought it was a great idea at the time because my stress levels were through the roof with finals. When you get the app you instead information about your well being, and they give you a path to take. Mine was about strengthening my relationship. I took it as a good idea to try and be a more positive and better girlfriend overall and had hopes it could help with our arguments. I showed him the app and the course and he got offended saying that it hurts him that I feel that our relationship is no good, that I feel unloved and have to go to an app for help. I tried explaining again why I got the app and why I thought it was a good path but he is very close minded. what would you guys do if you were in my shoes? I need help in solving this. any advice is serverely welcomed.
