This time in lockdown together will bring about emotional strain, as you probably will go through the motions of wondering whether your decision to split or want to end the relationship is the right one. There will be many opportunities for talking with one another, alone, and also many times when you’ll feel on your own, despite being isolated with this other person. Coaches are available for virtual sessions, should you feel like talking to an external person about your problems - should you be open to potentially resolving them. If there are disagreements about the separation, the opportunity to talk about things is something many do not get to do when we are allowed to roam free. Should it be a fragile subject and you be worried about your partner’s temper or actions, you must seek help and advice from authorities.
Many would postpone moving out or proceeding with divorce settlements etc. until we are further out of the woods of this pandemic - at the very least until the lockdown has been lifted. Both formal and informal separation agreements can be made between the two of you to make sure you’re on the same page about your forced cohabitation during this quarantine.
If separating or divorcing is a definite decision on both your parts, there is no reason why you can’t get the ball rolling by seeking legal advice and beginning negotiations but these would all happen virtually. Most businesses remain open, particularly those who can operate remotely. Should you need to seek legal advice, this is doable over the phone and therapists are offering virtual sessions. Those set on moving forward with proceedings should expect delays in the process due to the pandemic.
