Hello Solost - I am a touch concerned reading your latest posts that you are STILL in the belief that your H is "not himself" and that he is "a mess" and "all over the place".
Rubbish. Sorry, it really is absolute tripe.
HE is fine. He might be putting up some kind of "poor me, I still don't really know what I'm doing or why I've done it, it felt right at the time, not quite so sure now [that you appear to be getting away from him], will just keep you hanging on in the hope that I might change my mind" front - but HE is doing what HE wants to.
PLEASE get over this idea that he is having some kind of midlife crisis and that you should feel sorry for him - why the fuck should you? He has torn your family asunder, he has upset you, his parents, your parents, and not least his children! all for some woman who apparently is his "soulmate" (let us not forget that gem) - and it's not all quite as rosyposy as he thought it would be, PLUS he still has to deal with his responsibilities (and now he has new ones too). What a shame! what a crying shame that the moronic fuckwit couldn't see past the end of his dick to realise what situation his actions would create.
Block his number. Block hers too. You should have done this a while back - you are still using the frequent texting as a sign that he cares about you - he DOESN'T! He is doing it for purely selfish purposes - either to make sure that you are still all thinking about him, or to keep tabs on you, or to keep you believing that he cares enough about you to maybe ditch the bitch and come back. Whichever it is - NONE OF IT IS GOOD.
I am sure there is more for me to rant about but you STILL have a lot to do in terms of the emotional detachment - you are getting a small amount of pleasure from the frequency of his texts and misreading the motivation for them, and this is keeping you static, rather than moving forward.
You can try telling him to leave you alone; you can try telling him that you want to be allowed to move on - YOU DON'T NEED HIS PERMISSION! It all comes from within you.
Just do it - don't tell him, just tell yourself.
harsher than normal from me but necessary, I think.
