[Imconfused]

Last night my BF asked me why I love him. I told him because he takes care of home, he's smart, funny, good looking, he's a wonderful father to his kid and my daughter...and I said a few other things..then I asked him why do you love me...He said because you're my girl and the mother of our son..So I have to ask, What kind of answer is that. I am a little upset about that answer. To me he is saying the only reason he loves me is because Im here and he should and only because we have a baby together. In all the times I have asked him, that has been his answer.
Since I am here let me also ask this...We have been together for 2+ years, we have a baby together, we live together etc (everything a married couple has) except I don't have his last name blah blah blah...We were together about 5 months and he said I will marry you to put you on my insurance..I said I want to get married for other reasons not just that reason and he said he loves me. and I said if you really love me and know you want to spend the rest of your life with me...etc.... then yes I will marry you. Nothing ever happened...then about 5 months after he asked, I asked him..well he said no. So I left it alone...Then after our baby was born, yeah I brought it up again. He said he wasn't ready to commit to me. But he was ready to marry me to put me on his insurance after only 5 months of dating.
So why have everything you ever wanted in a woman...A woman who takes care of home. works..takes care of you and the kids..just about does anything and everything for you ...why not commit? He says he wants to spend the rest of his life with me but I don't believe him. What is your opinion???????????????
