Relationships...they can be both wonderful and challenging...so I applaud your careful consideration about
this situation with the woman at work...and how it might affect your current management plan/progress!
When you mention the self harm...was this you? Or someone else close to you? (I needed to edit the wording to avoid triggers for others and to conform to forum rules ..we can't use the 'S' word)
If it was you, and you are feeling shaky about
whether or not a relationship is a good idea at the moment, then taking things slowly would be a prudent plan. It may not be a matter of black and white...either an 'all in or nothing' type of choice here. You could choose to keep things casual, until you are more confident in your recovery...and where the relationship is going.
(of course, this could be a moot point if your company has a no dating policy, which many do. You will want to check on that to avoid either of you getting disciplined)
Consider all of these factors to help you know the best course of action for both of you. Best wishes and keep us updated, so we can keep you in support.
