How To Date Someone With Anxiety

So there's this guy I met on tinder and he is so sweet. When we had only been talking for a week I needed to see my mom who was in the hospital. I didn't have gas so he cash apped me 20 bucks . We've been on a free dates and he fiñally asked me to be his gf. The thing is he has bad social anxiety. I wanted to know how to date and be there for someone with anxiety. I don't know much about mental disorders
