Why do I get over people so easily?

Is it possible that you haven't connected to them in the first place all that much? If so, maybe consider why that might be?

Maybe you haven't found the true "one" yet. It is not a bad thing to let go of people easily because it would bad to hold on to people.

Maybe you weren't that into them in the first place..

Because I do not get too involved emotionally, I try to maintain my distance and avoid getting close to anybody

I get over people easily, because it's easy to forgive and forget over time. We all make mistakes in the end, and when we do, we move on and keep moving forward.

Because you maybe are not as attached to them as you think you are. Attachment makes things harder to cope with more often than not.

The few times I've easily gotten over a crush or out of a relationship, I always talk with my mom and friends about it, because it makes me wonder, why it was so easy to get over. After I've talked to them, I always realize, that I wasn't that into them. How I know it? Well a few months ago I just came out of a relationship, where I thought he was the one, and I'm still not quite over it yet. So I think why I got so easy over the past crush's and relationships is, because I just wasn't that into them.

It's possible you weren't very attached to them in the first place. It's also possible that you were attached to them, but you feel secure that they are always a part of your soul even though they are gone physically.

Because I am a surgeon, so as a defense mechanism in work, I pull back emotionally and eventually it became a part of me

It may be because you don't get attached to others as easy, it takes awhile to open up to them and to fully trust them.
