He says he loves me and wants to marry me

My BF and I planned our baby, I'm currently 4 1/2 months now and I don't feel like his first priority. He is very much a family man WITH HIS FAMILY. His mother, sisters and grandmother mostly. I don't seem to fit into that priority, one of the reason I fell in love with him is because he's so family oriented but now I feel like a left out step child some days. We haven't looked at any baby stuff and when I bring it up he's uninterested. Today he finally agreed to go with me and then cancelled and said I can go alone because he had a family event. I'm getting so sick of coming in last place to these women. At some point YOU HAVE TO CUT THE CORD. WE are starting a family and he has no input and no clue what's even going on and seems to think we have so much time he needs to think again and stop thinking other people are going to buy this expensive crap for us. My logic was to buy big stuff one at a time. This pregnancy would be so much better FOR ME if you was as supportive with me as he is with HIS family!

We are almost 30 and we have a house together.

Update: he always invites me and says they're my family to but I like my time with just our little family I don't want to spend every weekend over there. We have a house as well why can't they come over here sometime, I'm pregnant and tired and when you do go for what's suppose to be an hours turns into 4. Then I'm rushing to finish my holiday cooking or whatever I'm doing for us. I agree with you all about him growing up because he's never had a serious relationship before.
