"I think she was relieved when I started to get more distance and started seeing other people. I don't think I gave her enough breathing room, but we did get along really well. "
Hmmm. So, W had to get D to get the space she wanted. Perhaps the D would not have been necessary if she had more space during S. JustMe couldn't give her that space without the D and without dating. But, it is possible to give someone space without dating or getting a D. It is simply a matter of whether you choose to do it or not.
