I think she is!
We've got talking about babies, I said I'd love kids but my DP doesn't want them YET. We are 23, he is starting uni in sept, we don't live together. Plan is to get a house maybe a few years after he finishes uni, so about 30, then try for a baby when we are financially a bit more secure. I told her I'm a bit worried that at that age I may not be able to have a baby (I may not be able to NOW I realise that) but was just generally chatting.
She reckons I should just have one now and not let him know I'm trying. I feel thats tricking him into a child he doesn't want and is totally unfair.
We use condoms so not 100% and of course if one split and I got pregnant then we'd have to deal if it happened. But I don't think actively trying for a baby when DP doesn't want it yet is fair or any basis for a relationship.
Makes me wonder if her DP knew seen as they'd not been together long when her DD was born...hmm!
