Phone call with a “coach” that specializes in avoidant breakups. I’m depressed

I just got off the phone with a coach that specializes in recovering from an avoidant discard. Found them on instagram and there was a first phone call offer (just 20 minutes, free of charge)…. And that phone call got me depressed lol I gave them a few details (not many since it was just a few minutes) and at first they said my ex sounded like a very dismissive avoidant. Great! But then they told me my ex sounded like he had one foot in one foot out the entire time and that he had probably been talking to other women (since i told her that he’s now dating someone else and was thinking of getting into a relationship with her after only 3 weeks) and that he probably wasn’t as interested in me as i was in him. Because he clearly wants to be with someone else and is ready to be in a relationship with that person but he wasn’t with me. Because a man who wants you will not be busy, will make efforts to communicate, etc.. And now I’m like ..,ok so he basically never wanted to be with him at all? I was just occasional good company to him? I’m so sad I booked that call because it didn’t help me. Him being an avoidant was a bit of a reassurance. Because even if that ended and even if that was brutal, and even if my brain can’t still comprehend what the hell happened, at least i could tell myself it was because he’s an avoidant and just deactivated and then did the standard discard. But now after that call, I’m like “so he actually didn’t like me and wasn’t interested in me???” And man that is another punch in the gut. And I know I shouldn’t reevaluate again everything based on one person told me over a 20 mn phone call but i can’t help think that “what if that coach is right”?
