Relationship probz

I've been with this guy for 3 years but before him I talked to another guy that I use to adore and think he was the cutest and sweetest. But then he talked to a lot of girls and I chose the guy I'm with now because he never ask me out. Now I feel like I wish I would have waited and dated him instead because I'm having so many feelings for him and I don't wanna lose the good guy in with so idk what to do.
