you really should of thought of everything before you both got this far!
your fella should do all he can for u and ur kids if he doesnt then hes not so good!
jusy think how u will feel when ur here and the kids are still so young there,what happens when they get ill or have other problems will u be able to handle that and then act all happy when ur husband gets home?
u sound to me like a real mother u just need a real man to look after u?

you really need to have a long chat with him and tell him what u want from life and if he doesnt agree thats his problem!!
