New LDR

So my partner and I got together a couple months ago while both being on our campus over the summer. But by that time I had already withdrew from the school and was transferring to a different school very far away. He knew about it, but we didn't really talk about it at first and stuck with a see-what-happens mentality. Well, two months later I'm on my way to BC from NC and we said goodbye earlier today. We did end up deciding that we're going to try and make things work out, but he's been kind of iffy about it and worried about things taking a negative turn. Do you have any advice for what I could do to hopefully help with the situation? We're both going to be super busy with work and classes, and there's a time difference, but I really want things to go well. I've been thinking about writing letters/sending envelops with wildflowers (Since I often left wildflowers around for him) and maybe sending gifts, but he doesn't really like when I spend money on him so it would have to be little things. Is there anything else I could do? We're planning on calling as often as we can and hopefully video chatting. I just really want to try and make things work out well so any support or tips would be super appreciated.
