I ( 26 F) stopped caring what my long dis partner (25 F) does anymore. Is this something anyone else has felt?

Hello everyone. I just wanted to share a bit of context first. I never dated until I graduated from high school. I just never felt like it, never really like anyone enough to want to be with them or I just didn't feel anything for them ( I was always told you should FEEL something for someone)

So I got into my very first relationship after high school and BOY did I get taken advantage of. I definitely FELT something while being with this person. Lots of one sided conversions, being yelled at, ignored, put in weird situations blah blah

Took a year and a half of dating then them breaking up with me ( they cheated) going to therapy to learn that what I felt the whole time was just horrible anxiety. I generally thought what I felt was love cause no one has ever made me feel that way before. I feel stupid admitting my first relationship was some girl emotional, physically and financially taking advantage of me till she got bored and found some dude.

Now to my new relationship.

We have been together for almost 6 years. We are also planning to move in together. Things have been going and we have issues like everyone else but nothing crazy. Mostly lack of communication and consistently ( On there part, its something I bring up and they will do better for a bit then continue the same behaviors) Since being together Ive NEVER felt anxious btw. Just happy, sad stuff like that.

My current partner does things I don't like and they know I don't like it. We've talked about it over and over. Yet nothing has changed. I don't think I really even care anymore but I do work my self up over situations so that I do end up feeling something. ( I KNOW working myself up over it isn't good and I need to go back to therapy. )

Is it normal to just stop feeling sad/upset over things? Does/has anyone else felt like this?

They went on trip without saying anything to me till the day they left. I don't even know how long they will be gone or what they are even doing but I don't care. I tend to just feel whatever about thing then wonder if I need to say something again or just do nothing. In the passed I would have been hurt by it but i just happens to often that I just don't feel anything about it ( or I'm just trying to convince myself I don't )
