So that end comment is her telling u that she doesn’t want a relationship with u right now,she just wants to work and take care of her kids,my advice.....let her! Stop contact,more importantly stop all money,and I mean all,she wants to take care of her kids? Then their braces are her responsibility.ive heard of treat them mean keep them keen but this is someone just taking advantage of someone with a nice heart.until she realises this then u deserve the love u give out,this is all one sided and she’s making u sound like some crazy stalker that she wants nothing to do with,honestly I think back right off and see her change if she really loves u then she will realise what she’s done but if not then ur feelings sadly weren’t shared in the first place
