I don’t blame you, considering what you’ve been through.
At the risk of NAMALT-ing you, there are lots of good, nice, kind, decent, funny men out there. I am surrounded by them. All my friends have lovely husbands. Some I like better than others, of course, some definitely aren’t my type (in fact, none of them are), but they all have one thing in common. They’re good men who care about their wives and kids, provide for their families (albeit jointly with their wives), and who are a part of their kids’ lives - coaching sports teams and generally showing up.
I am lucky because I had a happy childhood with loving parents, and while that’s no guarantee, it does stand you in good stead. And it is luck - either you’re born into that, or you’re not. There’s nothing you can do to influence that.
All I can say is, if you do start dating again, ditch them at the first red flag.
If it feels like a niggle, it will be a niggle. So many people ignore red flags and hope for the best - ‘love is blind’ isn’t a tired old saying for nothing.
Bur the more red flags you ignore, the more bad behaviour you green-light.
And if you ditch in the early days, you haven’t lost anything. You’re simply single again, before your lives are intertwined.
Good luck.
