Hi liquidsnake,

Intense relationships are so awesome, and also really hard! I think you may both become really good friends over time, perhaps even more again one day…
Neither of you deserve any blame. People grow and change, and so do relationships. We all become a little co-dependent on our partners, as we give ourselves to the relationship. That’s why it is important (nice) to regather our ‘single’ self when the opportunity arises.
Taking a break is fine. Each of us have things to learn individually, as we are not exactly perfect :).
There is a grieving process, including self recrimination, at all these junctures. Don’t be too hard on yourself (or her).
Look after yourself, and keep the communication open and light with her for the time being.Things can grow into even better forms of connection, which are more stable and rewarding.

good luck
