Dating older man!!!!!

Hello Glow Divas... I'm 26yrs old dating a guy who is 39yrs old who will be 40yrs in September.

Should I be concerned because he wants a baby badly and he also wants to marry me but we have only dated since February. I'm HEAD OVER HILLS 💖💞💓💟👍💜💖💕💝💞💟💗 FOR HIM!😍. But he has given me until Christmas to decide if I want to marry him then he wants a baby is this weird or is this just luck???? I'm so Getty about him the very mention of his name make my heart pound heavily we have never been intimate with each other far as intercourse goes but were both very ready lol..... And I think tonight is the NIGHT! what do you all think????
