There are a bunch of reasons as to why they have changed their attitude or they’re starting to have an attitude. You just have to accept the change and love them or care for them, regardless of it. Although you may miss who they were, remember that time passes by so quickly. 

1. Pain changes someone. You can’t be traumatized at something and not be changed. Pain changes someone’s outlook on life. The way they deal with things, their tolerance, their patience, everything changes in an emotional level.
2. Loss changes someone. That’s a big one, especially when it comes to love. You can’t have someone heartbroken and not have their whole lives change. Loss of someone or something can change someone’s life. It changes their routines in their everyday life, their habits, the lost person’s influence in their life. It changes what they believe in and what they used to not believe.
3. Happiness changes someone. When someone or something new occurs, it brings fresh air and a new day in life. What someone used to think was wrong, they might think it’s right because of the happiness factor. It brings a refreshing sense, a hopeful view on how they will see things. 

Changes are inevitable. I’ve noticed a few times (more than a few times, I should say) that the majority of “change” is caused by negative events occurring in people’s lives. Moreover, it’s in negative things that we hear our calling, our purpose, our realizations.
