I was with my ex for just over a year around 6 years ago. The ending wasn't great due to his lies and cheating. However, I can confidently and truthfully say I'm over it now.
He was training to be a mental health nurse when we split. I remember him saying to me, 'what have you done with your life? Fair enough you have your daughter but what have you actually done with your life?' He said this near the end of our relationship. Coincidentally, I'm now in the final months of doing the course he did (have always worried this looks like I'm trying to follow him).
In spite of this, I genuinely believe he was a good guy. He keeps popping up on my people you may know and it's clear on his profile that he has a fiancé and a baby.
Would I be unreasonable to message him just saying that I'm glad to see he is doing so well and no hard feelings on my part? And congrats on the baby?
