Liking 2 boys at once???

Ok so I’m talking to a guy atm and he’s really nice and I thought I liked him a lot. I can imagine planning stuff with him in the future and I like his voice and personality etc

... but his best friend is someone I had a crush on for ages. I’m more attracted to his friend so whenever he sends me anything of his friend I find it hard to get him off my mind and focus on the boy I thought I liked. The next day I’m more focused again. I feel like the new boy is better for me and is defo really into me and would probs treat me better but I can’t help being sexually attracted to his friend. We used to talk!

What do I do? I need advice😂
