Do you have any thoughts on the fact that I became best friends with my ex's new girlfriend?
I might have some thoughts. Why did you become bestfriends with her?
I started chatting with her one day and realized that she's so kind and helpful.
Well, I think you did the right thing with regard to becoming friends with her. It is not good to dwell on the past and exclude people from your life, it will make you lonely. You should engage with her and see how the friendship works out.
I'm always looking for new opportunities.
I think it's great that you're so optimistic and on the lookout for new things to do and people to meet. I'm sure your new friendship will turn out amazing.
