well then that's good you offered
,has she ever asked for large amounts of money of expensive things ?
i've got 2 step kids, thou they are a lot younger than your g/fs, from the start they were included in our plans b4 we married. looks like you've both have not agreed on this yet. maybe you should ask her what she truly wants for her kids. as i've said maybe she is embarrassed to ask you to help support her kids.. so maybe your not being fooled
