Why would the other woman be mad at me?

Me & my bf were together for 3 years. He cheated on me with someone else & I let his sorry ass go. Well the other woman acts like she's mad at me & doesn't even want his family talking to me. She does not like the fact that his mother and family still favor me after all of these years. I have since then Married and moved on. What would cause her to still have an issue with me and she was the one who broke up my home?

Lack of confidence in her relationship. She is worried that his family will talk him back to you.

Actually, I ran into a family member of his and the conversation came up.I am the one thats married, they are not. Please know all facts before ASSuming and passing judgment. I really dont care just thought it would be an interesting question to ask. Is that so wrong?
