I'm sorry that you saw that, but I'm taking it first as it wasn't something sent to you, but sent to your DS's father???
If that's the case, then maybe you should stop looking on his facebook page. I mean there's no sense in looking at stuff that's just going to upset you. Like I said, I'm very sorry you're hurt, but my feeling is who cares, oh well if the Dad is trying to tell everyone out there that you're not a good mom, I mean yes it sucks that he's like that, but you don't have any control over that, and can't do anything to change it. All you can do is be the best mom that you can, and that's all that matters. As far as your DS's father not having him call you ect. for Mother's Day, well first it looks like your DS is 2, so I'm not sure what all you expect, but at that age, it's not like your DS has any idea what it is ect., so the only ppl. that are going to be sending you a card from him ect. are going to be adults, and if you and DS's father are not on good terms or he's not the type of person that cares about it, than you're not going to get a call or card. Again, I'm sorry, but it's nothing personal from your DS and again nothing you can control. Like I said, just make sure you're the best mom you can be, and your DS will grow up to know who his mom is and that's all that will matter. Good luck to you, but try not to let rude ppl. get to you
