Therein lies the billion dollar question...
Abusers are drawn to sucessful, popular, kind, considerate, happy people.... that are people pleasers, and vulnerable.
You have what they want, but your people pleasing, and often dysfuntional upbringing, where you're criticised, never good enough is what keeps you where they can wipe their feet on you.
The minute you give yourself an ounce of real self worth, it creates a force field that potential abusers can't penetrate.
When you get out, when you see how easy it really is actually to make that short leap to a place that is a million times better, you'll realise your own strengths, see your value and then, with a few minor tweaks here and there, you'll never need make the same mistake again.
Its a tough road sometimes, but omg is it ever worth it.
Have faith in yourself, you'll be better than you've ever been in your life whhen you do this for yourself and your dc.
One thing you must promise yourself though? That you must not limit the heights to which you will allow yourself to climb, take nothing off the table, even if you are not ready for whatever it is now, one day you might be. In the meantime, don't hobble yourself, or allow anyone to do so. No matter who they are.
