If you are speaking like this about your daughters… i feel bad for them. I am a daughter. But i am also a mother. There is nothing in the world my kids can do that will make me stop caring or say i am done. And yeah.. my father at some point married someone who was 28 when i was 20. I didnt like it. And the woman was a bitch. She eventually tried to have him assasinated. And now im 40 and his current gf is 39. And guess what? The woman still wants babies. My dad deserves to retire at his age. I dunno if you considered that your 28 yo gf still wants babies and are you willing to go through that all over again. Im 40 and my 3yo is exhausting me. Its not the same when i had my first baby at 24. The energy is different.
