need some advice
today started out alright then my sister called and asked me when am i gonna pick up the kids on friday. now here is the problem. i told my ex that i would start picking up the kids last year on friday and keep them til sunday. then when karen got pregnant she asked me if i would get the kids every other friday. so i said ok. only because she said she would leave and go back to carolina if i did not. now it has turned in to getting them every saturday and sunday and no more every other friday cuz karen is getting closer to her due date. that i can understand. but she keeps saying that i will not love this baby or even treat her like i do my others. she doesnt know that. i love my kids, all of them. i am trying my best i can to hold myself together with all this stuff going on. she keeps saying she wants to leave because i will not love this baby or anything and she really doesnt know that. my problem is, is that she seems like she wants me to give up on my three others and focus more on her and the baby. i am trying to do the best i can but i do have responsibilities with my other three also. i am trying to take care of her and the baby.i tell her if she wants to leave then leave, and i know it will hurt but what else can i do. it seems like all she wants to do is runaway from this than sit and try to work out the problems.i am always there for my kids and i pay my support and always there with emotional and physical support but what can i do. i need some help on this one. a little advice or friendship will do. i thank anybody who responds to this and appreciate the help. thank you.
