Hey BunMarley. I’m sorry to hear your new bun isn’t as welcoming as you’d hope. For some rabbits, it takes literally months to get a comfortable level with their owners. Some times, there are things you can do to potentiate the process, like give him food, be safe, non-aggressive company next to him, etc.., but there will be rabbits where, no matter what you do, will take a lot of time before “warming up”. There are also rabbits that may never really enjoy human interaction. I tend to think that asocial rabbits grow more comfortable if you 1) “invade” their space minimally in their presence (his pen, litter box, whatever it may be), and 2) you’re seen frequently, but never do anything that would frighten you (getting him to assimilate to your presence and realize you’re not someone who’s going to really mess with his life).
Since you’ve recently gotten this rabbit, I do recommend holding off on getting a companion— as you mentioned, it’s a lot of work to bond rabbits, and you want your current rabbit to be intimately familiar with you, and vice versa. Two rabbits could make things potentially more difficult!
