<human>: Can you condense the text into three sentences or less?

My girlfriend and I had been dating for 5 years, living together for most of that time. We'd been generally happy, and there was no infidelity, abuse, or anything that would otherwise make us hostile to one another now that it's ended.

Our lives really became closely intertwined: my consultancy does a lot of work for her charity; we have a house/cat together; many shared friends; etc. We've only been broken up for a day, but right after breaking up, we ran into a couple friends and went to the bar for drinks, and frankly it was one of the best times I've had with her in a while.

A big part of what precipitated the breakup was being unable to approach our relationship in a way that didn't add stress (it became essentially another to-do item on the list of two workaholics), and a sort of self-imposed isolation stemming from too much co-dependence, so neither of us were making new friends to replace the ones from before who moved away/had babies. We ended up together all the time, still having fun moments and good sex, but neither of us were really happy with our lives.

Obviously since it's such a recent breakup, and we were together for a long time, we're both in pretty bad pain right now, so I don't think it's a good time to plan any big life changes (like moving to new cities, or even taking new jobs). We both agree we don't want to lose the other in our lives. Considering how great we get along when we're not spending all day together, and when I can be relaxed in social situations because I'm not constantly worried about how she's affected by how I'm representing her. I think we can have a really excellent relationship together, so long as we're not a couple.
