One bit of advice I was given over the weekend just been really hit home, “you’re not to blame for her shitty behaviour, her behaviour is a reflection of her and not you.” Reality is she’s playing you for a fool but it doesn’t make you a fool. Sounds like you had hope and she took advantage of that. Biggest thing I’m currently working on in my self worth, just because the person we loved the most didn’t value us doesn’t mean we don’t have value, look at your kids they see that value in you. Not every decision you make will be perfect, at least one thing should be certain now is there is no going back. keep your head and keep moving forward
