I’ve distanced myself from him when I felt he was overstepping what I was comfortable with, and he seems to have taken that on board now since I’m showing him I don’t want to accept it instead of just explaining. He has maintained more of a friendly interaction rather than flirty one since.

You’re right actually about being interested in others if he weren’t an option. I think if I didn’t see him as a potential option it would be much easier to focus on someone else when the time becomes right. Even though I still have some milder feelings for him now I’d still be prepared to go out and date others once I feel ready to (when things unrelated to him are sorted). I just haven’t felt that strongly about someone for a very long time which is why it’s beenn so hard to let go. I’m still not sure if it is right to let go or not in all honesty.

Your words have been extremely helpful though and given me some valuable food for thought.
