NC day 7

I'm struggling today.... NC day 7.

I feel this big urge to just message him to resolve things. Not to get back with him but to let him know how I feel about a few things and to clear things up.

I know I have to keep NC but in struggling today.

Part of me knows what's the point.... He's been quite happy to not contact me for 7 days an that should say something but then another part of me thinks ..... Oh I just want to let him know this......

Still finding it hard to believe after 2 years it's just ended like this :(

Advice? Does anyone else feel like this?
