OP
>>21453715 you have 5-8 years since you first started dating to impregnate her. After 5 years she will start to fall out of love with you. If you do start a family this won't happen (unless there are unlaying issues of course). Don't take it personally, it wasn't you as a person it's just how it is.
This 5-8 years is programmed into women and men's biology. If a man hasn't impregnanted her in this time frame the lizard brain comes to believe he is impotent/infertile. It's evolutionarily successful trait to move onto someone else who will impregnate, since to be with someone who is infertile is prema death for her genes.
