Broke up with my LTR of 6 months yesterday. I think I did the right decision.

For some context, we're both university students and live in the same city. A few months ago I went for Christmas to my home place. While I was there we would occasionally talk via text or facetiming/phone calls. I'm not really into texting and I don't agree with constant everyday texting. That's something I told her from the start. I usually only use text for logistics or to see how she's doing.

For her this was apparently an issue(never said it was btw), but it's something I was multiple times clear about it from the start.

When I returned she told me that she felt we had communication issues when we are not together. Like we have nothing to talk about and/or I don't care. I said that this is just me and I'll try to communicate more if that's what she wanted.(Red flag n1, that's when I realized something's wrong)

Recently she had a urinary infection (or at least that's what she told me) so I couldn't she her because it's very uncomfortable for her, so we would talk a bit more often. She 80% of the time texts me first, if she doesn't I will probably text her the next or the same day, depends if I'm in the mood or not. During her away period, I would mostly just check up on her, everyday same shit, she's bored, in pain, doesn't do anything etc. Nothing really to talk about unless I call her and talk about my news or whatever.

Guess what happened, she complained about the same problem again, how we have nothing to talk about,our communication isn't there, we haven't "moved" more in the relationship, keep in mind , all of this, when we are not together. Nothing of this applies when Im with her.

She says everything's perfect when we're together but when we're not we grow distant.

She says it's the best relationship she ever had, everything's perfect except this.

I tried to understand her point of view, yesterday we went out and I talked to her about it. She doesn't know what the problem is, she doesn't know what she wants.

She says something's mission from the relationship but doesn't know what.

I told her that we could work on it and it's virtually a non problem, I suggested we facetime or talk over the phone since it's more natural for me. Problem is, she doesn't think we can and doesn't know if she wants to try working things out.

She says something's mission from the relationship but doesn't know what.

So I did the only logical thing and told her that we should break up and figure out what she wants/work on herself.

She wasn't expecting it but agreed, was very emotional, crying etc. No big fight, nothing, it was a very good break up.

So, right now I'm confused. I truly don't understand what went wrong. Any advice guys? She says it's not my problem, it's hers, but I really don't know. She obviously wanted something I cant give her but what?

Keep in mind this girl has been an emotional wreck lately. She was sleeping or day or watching Netflix. She mentioned she also had depression.

Thanks for your time and sorry for the long post.
