What Can I Do?

I'll start from the very beginning; I had just gotten out of one abusive relationship, only to go into a very short-lived one with a man who didn't actually want to be with me like he had said. So I went on vacation with my family, and not even a few days later of coming back from California I got a match on Tinder. And I'd only just started using Tinder, it wasn't really something I was super into. And if I hadn't found a guy that I liked soon, I was going to delete the app and just assume I was going to be alone forever.

Well, it turns out the day I decided that I was done with the stupid app I got a notification that I had a few matches. And one of them was this dorky looking blonde kid, he had a goatee, and long hair— which was hard to see because he always had it up in his pictures— but I decided; why not? So I swiped right and we began to talk, a lot. At first, I was extremely nervous. How was I supposed to react to meeting a guy from the internet, so instead of going on a movie date like we had talked, we went and saw the opening to the Ogden lights (we'd been talking for a little under a month at this point) and I suggested a double date with my sister and her friend. It went as I expected, I was nervous, and a wreck. I dressed nice, he looked amazing, and I couldn't even muster much more than a few words.

Well come the week before Christmas I was nervous of whether or not he was going to be happy with my gift, I bought him a haul of CD's since music is his favorite, and when it came to exchanging gifts we did it in my room under a tiny pink tree my sister gave me. Mind you I was nervous, here was this guy I met on Tinder a month and a half ago, and now I felt like I'd known him my entire life. I prayed that he'd be happy with what I had given him, and he was. His gift to me was a mixtape and some gaming dice for Dungeons & Dragons because he knew I really wanted to learn to play.

And on December 31st of 2017, he asked me to be his girlfriend. He had been nervous that I was going to say no, so he talked to my sister about it who told him that the easiest way to get me was to be cheesy about it— because I'm a hopeless romantic and love that cheesy crap. He made a really cute cheesy sign that said something along the lines of "I know it's cheesy, but I'd really like to start the new year off right.." and then he asked me to be his girlfriend, and I, of course, said yes.

It's a little over 6 months later and I'm still falling in love with him. Every single day. Honestly, there's nothing I want more than to spend my life with him.

My problem?

How do I show him that I love him as much as I do when he won't let me buy him things, or do things for him that will help him? He's so bent on believing that he doesn't even deserve the love I give him every single day. And it breaks my heart knowing that I can't show him the same way he shows me.

So this is me asking people for help and advice on what I can do to show him more of how I feel.
