I've seen people do terrible things both on purpose and on accident. Doesn't make you a bad person or this other person. Then again I can't say much since my friends seem to think what I did was horrible and now I'm so bad person for doing what was needed.
If everything in life was easy, it would be boring. Leaning to work together will take time, but it will become easier. We can work out a time for us to work on it.
