Thanks for sharing that. I realize you can never say never, but at this juncture I can’t imagine parting ways with H. and then allowing him back into my life.
Totally understandable, but here's the point: At that time, it's *your* decision. In other words, if you got involved in Ls and court and all that garbage, that doesn't mean that H isn't going to come back around. So don't let that worry you if you *must* go through mediation or courts or whatever.
However, if H does eventually come around, you certainly get the final say. And you don't have to figure out today or tomorrow or this week whether you'll take him back. You can wait to figure that out until the day he comes back.
Put one foot in front of the other, try to put your R with H in the back of your mind and let the cards fall as they may. Hang in there!
