<human>: Can you give me the gist of the text in a nutshell?

My girlfriend and I recently stopped living together after 1.5 years. We've been together a total of 2.

Things were great at the start until about 5 months in, where we started having problems. I had some old baggage that I had to resolve myself, so I started going to therapy and working things out. She threatened to move out because of my problems, and actually did for a few days, but came back. We resolved our problems, but they arose again a year later (about a month ago). Not the same problems, but this time it was some problems she was having. The household became really toxic and she decided that she didn't want us to live together anymore. I pleaded for her to stay and work on it together as a family, but she decided that we should live apart and work on ourselves.

We've been living apart for about 2 weeks now, but I haven't seen her at all since she went on a family trip. She's back now and wants us to "work on our relationship." I'm wondering if I should even bother because I feel a sense of resentment toward her for breaking us up (in terms of our living situation.) I also don't feel like I can trust her - I look toward the future and imagine us having kids, going through a difficult time, and then her deciding to break our family apart again.

What should I do?
<bot>: After living together for 1.5 years (out of our total 2) she decided we should live apart "for a while" to work on ourselves. Should I just call it quits now?
