I was about to post from opposite side of this. Me and ex both live off one of the main roads here. Ended up behind her car today and it sucked. I turned off early from where I was headed, sat for a few, then drove on. Felt guilty even though both the university and medical district on same main road so it makes sense occasionally would end up bumping into each other. Really, really wanted to contact to explain that to her and nothing untoward meant at all. That was just excuse though as mainly just wanted to talk to her for a few to see if the nice side was there today. Hang in there. It's hard. I know for a fact it is so, so hard, but long run we will be better off having healed.
