Is there any way out of the slow fade?

I’ve recently come to the realisation that my last 2 partners were both FAs and both did a slow fade on me. I took a different approach with both but both had the same outcome.

With my ex bf, it was a longer slow fade. I asked if anything was wrong. He said I don’t know, stop asking me. I kept asking with each slow fading action he showed me. Each time, told me I was inventing problems and to leave him alone. I even asked him directly if he planned to break up with me. He angrily said no and that I loved creating problems in my head. We started planning to get a deposit for a flat together, planned a holiday for my birthday. Then one day in the middle of a restaurant on a date, dumped me.

Next with my ex gf. It was like a switch flipped out of nowhere. I only asked her once time during the slow fade if something was wrong. She told me her dog had died and that’s why she was acting off. She’d never even told me her dog was sick, so I told her I am always here for her and to speak to me if she needed support. I didn’t ask again, didn’t hound her, I was loving and attentive, hoping she’d come back or communicate if there was an issue. Things started to improve ever so slightly, we had a good weekend where I met her friends and she initiated future plans, then she dumped me.

Currently in therapy and working on finding out why I keep attracting FAs, working on my communication, reaching out to friends, staying out of the dating pool and self reflecting. I’m wondering if anyone had any experiences where they did the same or different things as me, and what the outcome was? Does a slow fade just inevitably end in a breakup, or what are you meant to do?
