Boyfriend’s ex

My boyfriend’s ex (they dated literally 10 years ago) recently got out of a long relationship. She and my boyfriend stayed in touch here and there throughout the years, which is normal because they dated when they were children.

Now that she’s single, I think she’s reaching out to him for attention. It usually wouldn’t bother me but she’s trying to get a hold of him in every way possible ...text, social media, etc.

Would anyone else have a problem with this or am I just being insecure?
