Should I give up?

I'm just going to drop the ball on this and say it... I love my boyfriend, but he's addicted to work. He is 46 and has been married before. So he's not super into the idea of long-term commitment anymore. I think he doesnt believe it's achievable forever.

I've never been married and I am 32. I hope to be some day though. I love communication and touch, and I need to see my partner at least 1x/week. He can go weeks without talking or seeing me, but he still loves me. He just gets consumed in work.

I tried talking to him about this last night, since it's been about a month since we've seen each other in person last. When we do see each other in person, it's magic, but I need the continued long distance communication to keep the flame burning. The longer we go without talking the more anxious I become in the relationship and unsure of how he feels.

So anyways, I brought this up to him last night and asked him what the minimum and maximum time he would ideally like to have together. He asked me and i answered, then I asked it back. In response he said, "This is boring. I dont want to talk about it." I explained that I dont feel good when we rarely see each other but if there was some limit/standard/expectation it would make me feel more secure in the relationship. He said "That's too mechanical." I continued to try to explain, but it seemed like he was getting bothered by the idea of talking about it.

We currently see each other in person about 1x/month. We live a 5 hour drive from each other and it's a 45 min flight.

It started out as a phone call, then went to text. Here are the messages from that conversation.
