Don’t want my AA to ruin a good relationship

I was recently left by someone who told me I was too much. And this really made my anxiety hit the roof giving me a panic attack.

I am now talking to this new person who is amazing and so good for me. I would reveal parts of myself to him and would somehow wait for him to tell me I’m too much. But he matches my vulnerability with his. He makes me feel calm and safe and has never once given me a reason to be anxious.

But every once in a while like tonight, my anxious attachment hits me hard. I’m getting scared thinking, what if he just wakes up one day and realize that I’m too much for him. What if he sees all of me and he changes his mind. I start to overthink and just my brain is spiraling.

How do you guys stop this? There’s really no reason for me to feel this way. And I really don’t want to ruin what we have because of this.
