Please help...do you think he likes me?

So i work with this guy and lately we have been able to work close to each other and are able to talk. We have a lot of fun together. We both have very sarcastic humors so we have continuous sarcastic banter which is quite fun. Lately he has told me many times how much he enjoys my company alot and he said he likes it when i work around him. I know everything i am saying is positive and thus that might bias your opinion. I just am really starting to like him a lot, and want to know what it means whn two people continously just go at each other with sarcastic banter.
