Starting to see some positive results

I am about 2 weeks into NC with my ex and am starting to see some positive results which is very encouraging. First off, last weekend she casually contacted a mutual friend…coincidentally the same friend I was out of state visiting at his college to go to a crazy Halloween party. The same night as the party she sent me a few snap chats which I opened but did not respond to. Sunday after I left for home she contacted our mutual friend again and although she tried to say it was “catching up” they are absolutely not the type of friends that would casually talk like that especially not all of 2 hours after I had left. A few days later, today, she liked and commented on my new profile pic, which is something she never has done before even when we were dating. Overall, it looks like she is starting to get curious and is “checking up” on me as subtly as she can. I am feeling pretty encouraged by what looks like positive signs and I plan to continue NC but anyone have any thoughts?
