After three years of no contact, I woke up to a message from my ex

>Hi, Anon! Sorry to bother you this early. I had this weird dream about you and I just don't get why I did. Hope you're doing fine. Feels like I can't be at ease without knowing the reason, it's the first time that's happened to me. No need to respond if you're not interested. Thanks! (sparkles emoji)

What did she mean by this? I got a cute new gf of two years now, and life is great, she's really sweet and actually makes me feel loved, unlike my childhood friend ex who acts like an archetypical tsundere who communicates like shit especially with that above vague wording she uses all the damn time.

I thought my ex moved on and forgot about me already. I do not want to go back to her. She's hot, but makes me feel like she hates me half the time so I have no idea how I put up with growing up with her since we were kids. My new gf is the first time I actually feel valued by someone loving and caring.

How should I feel about this? I know her like the back of my hand after being with her for so long, and now that I know what love actually feels like, I can see objectively now that she is not the right one. I am glad she's gone. I can never put up with someone like her ever again.

But still, a tiny part of me misses her and wonders how she is doing. I hope she is doing well.
