I honestly think that a break up with a small bang involved can be a huge red flag. It’s tough on all couples but, it does indicate a failure to support or understand when things aren’t easy.
I hadn’t really realised this, but with hindsight, I should have been much more wary of STBXH. He had separated with a baby c. 1 year old and I met him about 8 months later. He seemed great and his break up story had been that his ex had cheated on him. although over time details emerged that he had been planning to divorce her anyway because she’s dreadful and, actually, he was cheating on her, and so on. Anyway, I didn’t discover this at the time or think enough about things.
We had separated before our baby was 1. And things had been really bad from during the pregnancy. He was just completely incapable of stepping up and being there when I needed him. At all. Quite the opposite. And far too selfish to cope with not being the centre of attention. It got worse and worse (and he was awful) until I left.
so a story where they had a small baby and he walked away, leaving her devastated, because they ‘fell out of love’ sounds suspicious to me. It doesn’t sound like a man who is anything but a fair weather partner.
My STBXH is now a man who has had 2 marriages fall apart in the first year of a child’s life. It is a pattern. So I hope it’ll be more obvious that he should be avoided to anyone else silly enough to consider a relationship with him.
