First Break Up

I just broke up with my 9 month LTR last night and I’m trying to move forward.

My life is fully in order, relationship was great but I want to be alone and work on myself some more.

I didn’t plan on doing it, but one thing led to another and it had been on my mind for awhile.

Now I’m fine, I will get over it and I’m not really worried about that.

But I feel horrible for her, she was sobbing and begging me to stay, saying she doesn’t know what to do without me. And honestly I just feel like shit, bc she didn’t deserve it, and there wasn’t a “reason” for us to break up. I just want to be alone

How do I get over the feeling bad about it part? This is my first girlfriend, and first break up.

I still lift, eat well, focus on my mission. I’m not asking how to get over her, just the feeling bad aspect of ending things with someone you care about
