Our men

Ok so i really need advice and truth to ease my mind. My fiance had 5 other children with another woman, they were together for 13 years. I have one child with another man which we were together for 2 years. When i was pregnant with my first child, my ex never showed me any special attention ( belly rubs, foot rubs, help saticfy my foods cravings, etc). I am now 9 weeks pregnant with my fiances baby and he tells me all the special things he used to do for his ex and all the special moments. He hasnt shown me anything like what he did for his ex to make he comfortable during her pregnancies. I personally feel like all those special moments were wasted on her. The only special moment me and my fiance had was when we saw the babies heartbeat and that 3-4 weeks ago. Idk what to do or think, my head is spinning in all sorts of directions. I feel like his ex was the love of his life and im just somebody he can tolerate living with. Ladies help i need advice or guidance
