My heart hurts so much ...

My husband and I have been together six years. I have a child from a previous relationship and earlier this year me and my current husband welcomed a baby. Well today in our conversation I realized my husband “puts up” with my child because they are mine. He doesn’t love them because they are apart of me and he loves me so much... he tolerates them.... this crushed my heart... after six years I truly saw him for who he really is and I just don’t know what to do.
