Is my ex an avoidant?

5 years together, over the holidays she came out with an elaborate plan to get rid of me, she cohorted her kids to not want me around with her anymore, but I also found out she’s been secretly going to another guy’ hotel room everyday before going to work since beginning of December, she kept the lie for about a month till I finally found the other guys number I found out the other half truths that she’s been hiding from me,

for me it felt like she used her kids to get rid of me so she can be with this new guy, she’s been doing her best to avoid any conversation with me,

last time I spoke to her all she said was you already found out the truth now leave me alone, which I did but I still try to call her from time to time at this point I don’t even why I’m still trying,
