New relationship and texting issues

So I'm seeing this guy, and it just kind of evolved into a relationship. I recently confessed my feelings and he came back with his and said that he loves me. We see each other about once a week. We live an hour apart and he has a son that he's with frequently. I'm honestly okay with the 1xweek thing, he's an amazing dad and I fully support him spending as much time with his son as he can.

Anyway, when we're together in person he's affectionate with me, always wanting to touch me and our conversations never end. BUT..texting is a whole other story. He's really dry, doesnt leave much room for conversation, and isn't affectionate in his words at all. He started a new job on Monday and since I might get like 4 texts a day, no goodnight or good morning messages either. His work day now starts at 5am and goes to 2pm, so I know that they're weird hours. I'm hoping that maybe the lack of conversation is just being busy with training and tired from trying to adjust to a new schedule.

I was with him last night and made him dinner, things were great, he's still saying that he loves me so I know that we're not in a rough patch or anything. We also have an age gap, and not by a couple of years, it's pretty significant (please don't come for me that's not what this post is about). So maybe he's just not really big on texting?

Thoughts?
