Wait until we're 50? Say wha?!

[heatherg]

I used to post quite a bit here, usually in the infidelity or SSM forum. I never had a SSM, but I grew to like many of the people that posted there and so that's where I posted. But, many of them have since left but that's neither here nor there.

I wanted to pose something to you guys and ask your opinions because maybe I need to widen my perspective. My H has always been very, very occupied with our kids. We have a great family and we do lots of fun stuff together. My issue is that H never seems to think time with just him and I is important, not even to go to a movie much less spend a weekend away. The kids are getting bigger and it's not as easy as it used to be to sneak sex, etc.
H wants to have another baby. Now. I told him I'm still interested in having a marriage, so he's going to have to get better at date night or something before we have more kids. I told him if have more children, we'll NEVER have time alone. He's out of town, so this conversation took place by IM. His reply to me was so far out there, it made me laugh. He said something to the effect of "I just envision such a relaxed time in our 50s or so, we'll go places together and miss the grandkids and get to come home and spend time with them....we have so much time for us later but the time for more kids is running out." It floored me that he seriously suggested we wait until we're 50 to have date nights or spend time alone together and it also floors me that he's already envisioning how close we're going to be to our grandkids.....our kids are 5 and 7. WTH?
He gets very defensive on this topic as well....I would think that me wanting time alone with him would tell him that I still love him, still find him attractive, still want the romance, etc. But he doesn't seem to care about any of that.

Any suggestions?
