I'm 21 and my girl friend broke up with me mid January on my birthday. Even though she said I did nothing wrong, I feel like I was incredibly toxic towards her, and dragged her down. How do I forgive myself?

First of all sorry to hear about the break up. You say you feel like you where toxic to the relationships I think the first path to forgiving yourself and moving on is to reflect on what happened during the relationship and truly understand What happened. I feel like then only you can take the steps to forgiving yourself and moving on. That in itself will also take some time. Although forging oneself will be the most important part because if you don’t forgive yourself you will be stuck in the past and won’t be able to move on happily. All the best. Peter

Forgiving yourself for hurting another isn't simple, agreed. Maybe start with working on becoming a better you, and figuring out what you could do in the future to prevent the same thing from happening, and then try again?

Always know that you gave your 110% in the relationship..It might not have been the best 110% but u did your best anyways..Whether the relationship works out or not is beyond your control..All you can do is learn from the mistakes and make yourself better in whatever you do..
