Help me settle this ladies(comment)

So a friend of mine and I were talking and she mentioned that her ex’s brother had been talking to her calling her princess and other things, now he wants to take her out for lunch and go do other things with her.

I believe it’s wrong and she’s conflicted with how she feels even she thinks it may be wrong

She only dated him for about 2 weeks and then was on and off with him for 2 years(she was 17) and now she’s 19

What are your thoughts ladies? Maybe I’m wrong she wants to see others opinions
