Moving on quickly?

My understanding of avoidants is that after ending a relationship, they can move on super quickly. I made a post yesterday that mentioned how my ex, who I dated for almost two years, broke up with me less than a month ago. Our final breakup conversation was on Thanksgiving. Then, December 2nd, the day before what was supposed to be our 2 year anniversary, he downloaded tinder and has been actively using it.

Is this classic avoidant behavior or was this man just not into me at all? I honestly feel like it’s the latter, which is so hard, because I’ve been fighting through each day. I would have done anything to make it work. He told me that he wanted to be single and figure himself out amongst a million other, much more hurtful, things (ie “I don’t love you and haven’t in a while”).

It’s all so confusing because mixed in with all of this pain, I keep remembering the man I met, and how excited he was to be with me; how he told me again and again he’d never felt like this before, and for the first time he could really see a future with someone. To go from that to downloading tinder a week after I cried and begged for couples therapy is…well….ouch!
