We've been split since before lockdown. He was a big liar, pure hedonist and all about his own instant gratification and a slippery, gaslighty so and so but was always really lovely to me, just a little bit of a cunt behind my back.
Anyway, this time last year I was involved in something really traumatising. He was completely unsupportive, I was very ill with ptsd / cptsd and a big part of the illness was because of his deceitful and downright selfish behaviour at the time I needed him and he was away with an ex: in a group of women about which he'd been absolutely silent prior to going, I had no idea about the group he was with nor the ex. not the first time this had happened but last time was a different ex. He even had the audacity to tell me afterwards that he'd been wondering beforehand whether there's still a spark between them...I found all this out whilst reeling from the traumatic event and it really hurt me.
From various bits of evidence, and things he let slip, I'm pretty sure that he was never faithful, even without that trip.
I clung to him after the trauma because I was not in my right mind and needed him around. Of course, his presence actually made it worse.
In our final weeks together, more and more stuff came out and in the end I found the strength to end it.
I was heartbroken, mainly due to the deception and the loss of the good stuff we had and of course wondering if it was all a lie and torturing myself with ruminating on what he'd been up to.
Anyway... We kept arguing about it as he was adamant it was all my issue and because of the ptsd, so after fruitlessly trying to get him to see my point 
I blocked him and then he'd find another way to contact me until I'd blocked him on Al platforms.
then he wrote to me saying that I have commitment issues which is also the story he's telling mutual friends.
Fine, I don't really care have been over him for months he can say what he likes if it helps him to keep his ego afloat.
So, today I received a stunning bouquet through the post with a card basically acknowledging that this is the anniversary of the traumatic event and suggesting that I must be having a difficult time. In actual fact I've been having a ball.
I'm pretty sure that he only remembered because the anniversary also coincides with the yearly trip he took with the ex.
I had acknowledged the anniversary to myself and gave myself a pat on the back for how I've found my way back to 'normality' after a horrible breakdown.
Difficult to say too much but the original event had repercussions which actually carried on into this year and I have changed beyond recognition as a person because of it and I am still feeling reverberation s despite being so much better and am awaiting further therapy. He always pops back up when I'm in a 'good place' and since hearing from him I've started to have anxiety butterflies / palpitations which I haven't had for a few months and am feeling quite vulnerable now.
His card was advising me that the past is gone and to let go, or some such crap.
He knows I'm a polite person and would be likely to acknowledge and thank him for the flowers but ii feel I've come a really long way and don't want to reopen the communication with him.
So really I probably don't even need to post this as I've answered my own question but curious to know whether any of you would respond?
