im so sorry about your situation... its a horrible thing for her to make you look like a bad person to your daughters... that is just utterly disgusting and im sorry she is doing that to you...

i am not good with advice... but i want to offer what i can in terms of what i would probably do... i am young though so who knows if its the right thing or not...

i would move in with the gf... if you are happy with her and she is happy with you and you all get along and she wants you to move in... then i think thats a good thing and i would really do it... because everyone deserves someone to love them and treat them kind... make them feel special and wanted... all of those things you know...
yall could work together on bills and you would eat better....

becareful with the childsupport because as far as i know the state can get involved and even take you to jail..? i dont know how it is in NC...
its a really sucky thing...

you have to take care of yourself... be kind to yourself... you deserve to be happy... what your ex is doing isn't your fault... she shouldn't cause you so much pain....
that really sucks... im sorry about it...

hopeffully as your daughters get older they will be more interested in seeing you on their own... instead of listening to all the things mom is feeding them...

but through out it all you need to take care of yourself... you being sick and unhappy isn't going to help anything right...?
you do deserve to be happy and thats what you should focus on... do what you can to make your life better, make a life you can be happy with...
it sounds like your gf is a good person and her kids like you so thats a great thing...

have you considered getting therapy...? maybe a few sessions would really help you process some things and work through some things...

please take care of yourself...
