I think the narc is back!

Hi guys! A few months ago when I decided to go NC I went and took out a new contract for my own mobile phone as my old contract was still in my ex narcs name and wasn't due to end until June. As I didn't want him having any hold over me anymore I got my new phone with my new number on. He knew after a few days that I'd changed my number as he texted and I didn't reply so straight away he was texting old work colleagues to find out if I had changed it n they said yes but we can't give out her number as she's asked us not to. However a few days ago my daughter lost her phone so I said to her if my old phones still working then use that for now I'd deleted his number off ages ago. Within four hours of her using it he sent a text sayin are you still using this phone in which my daughter replied "who's this? It's her daughter" I don't think he'd have liked that some how! He tried to engage in conversation with her and then said I hope you and your mum are ok!!!! What a complete arsewipe!! He must be constantly checking my phone calls n bills to see what I'm doin if after 4 hours of her using it he texts! Somehow I think he was trying to worm his way back into a conversation however I didn't engage with him and deleted the msgs n took my daughter for a new phone! Honestly the first little gap of contact n he's straight in there! I did feel a slight gutting pull of being sucked in but I felt my protective guard come up n I thought no your not doing this to me now! I just wanted to say I KNOW WHO AND WHAT YOU ARE!!! But he wouldn't care he's not made that way! I'm proud of myself that I didn't fall back in n it's even nice to say I'm proud of myself I haven't said that in a long time but I'm proud! My cbt starts Monday and I think I'm starting to feel like I'm going to be in a nice place soon xox
