Children in my opinion are generally blessings if thought about and planned, not sure why they wouldn'nt be woofgang, unless i'm missing something here?
Jenarry, if you feel this strongly about this then you and your partner need to sit down and talk it through. You then might be in a situation where he can be persuaded or alternatively he might not, that leaves you then with the decision of whether to continue the relationship or not. Either way saying nothing is not really an option, as although women have kids well into their 40's, time is certainly not on your side long term.
