I want a baby

I'll try to keep this short.

My boyfriend and I have been together for almost 3 years (we had a bit of a break the first year we were dating but got back together and all has been great)

His work is kind of weird. He loves it and I don't have a problem with it! Its just that he's gone for 5 weeks then back home for 1 week and so on.

We don't live together. He has two kids from a previous relationship (a 15 year old and a 13 year old)

I really want to have a baby (not to be rude but time is ticking! I'm a lot younger than him so I don't want to wait forever!) And he said he'd like to have a baby with me too. But since his new promotion he's like I don't think we should because he's never around.

I get kind of lonely. Like he just bought me a puppy the last time he was here at home and I house sit for him, drive his kids to school occasionally and whatever but I really want a baby with him I want that intimate connection I want a piece of him a mini us!

I respect him he's everything to me. I want to just tell him to not use a condom and not to worry. Advice??
