Getting into a new relationship so soon doesn't resound someone who worked on their core issues. It sounds like a way to fill the void. It sounds like something to do in order to have a clean slate leaving unresolved issues from the last relationship.
My exH has seen therapists and has some experience himself of counselling skills. This is partly why I continued to reconcile repeatedly - he had insights about his behaviour and he was seeing T. He seemed to be dealing with some difficult stuff and really trying. However, from my viewpoint, he gets so far with addressing issues and then stops.
When he left last time, he went on a course and later did send an apology of sorts - by e-mail. I was still reeling from yet another totally confusing breakup with no closure and yet I did not 'push' him because I knew that the course had been disturbing for him (though helpful) and decided that it would be best not to invalidate his feelings at that time (even though I was extremely distressed by the 'apology' that somehow managed to point out my flaws ... . again). I thought that after some time working on himself, we'd be able to have a mature, adult conversation. I didn't expect to get back together (this time, I was too angry about the way he 'disappeared' on me) but I did expect that after a near 30 year relationship, we'd talk about stuff.
Instead, he was already dating within weeks and got married six months later. I want to believe that he has addressed his issues and is now in a healthy place - best not just for him but for our kids and for me. Best for his new wife. But can he have dealt with major issues in the few weeks between the course and dating again?
Significantly, I have realised that there were some core issues
I needed to deal with. I had seen T previously but was still in the 'FOG'. This new T has really shaken me up. I was in the perfect relationship to distract myself from my issues!
Whilst I think we can support partners, we can only really deal with our own stuff and change ourselves... .
