How to thank a man?!?!

To start out, my boyfriend is an absolute freaking godsend, I don’t know what I did right in this life to call him mine. But yesterday, we went out had a couple of drinks and shots apparently and stumbled our way home around 1. I don’t drink much usually, and for someone who’s all of 120 pounds and 5’4” it doesn’t take much to get hammered quick. I blacked out somewhere around 11 so this is all secondhand info, I not only puked out the window of his car but also on my bed and carpet. This man, not entirely sober either did my freaking laundry and helped me shower, brushed my hair, and got me dressed. We ended up spending the night on the couch after he did damage control and got everything cleaned up (even tho he put the laundry detergent in the fabric softener spot so they didn’t actually wash the first time- it’s the thought that counts). Words can not describe how much I am grateful to this man. Which leads me to my question; ladies how do I thank him and let him know how much it means to me?

Edit I feel like I should add he is over 21 while I am not, and we’ve been together 5 months
