Breaking (26F) NC with ex boyfriend (26M) after 4 years?

Hi all.

So my ex boyfriend and I broke up ages ago (2020). I visited him in the States 4 years ago (Spain-US LDR) and at that time we had been broken up for about two years. Deluded by my own delusions, I thought it could have been my last chance to get him back, or at least to have a 'situationship' moment with him. He had made it clear to me that nothing was going to happen between us prior to the trip, but again, I was deluded by my own delusions.

After the trip we ended up being in bad terms. Self awareness is important, and as I have stated before, I was deluded, but looking back, I feel like the way he treated me wasn't right either. Anyways, I did end up learning my lesson. After the trip, I told him it would be best for me to remove him from my life and to go no contact, to which he agreed.

Fast forward to last summer, I get a dm from him on IG. He texts me about the new season of a show we used to love watching together; he was letting me know that my hometown in Spain was getting featured on one of the episodes, and that I should check it out. We texted for a bit and that's it.

I have been thinking about reaching out and just asking how life is. I'm at the point of my life where I don't hold any grudges against him and I don't have feelings for him either.

Is reaching out that bad of an idea?
