Is it normal to have second thoughts about a long-term relationship occasionally?

Coola • Cali girl by heart
I've been with my boyfriend for a little over two years. I'm in love with him & he still gives me butterflies but there's just some days where I get so bored with him? We have similar opinions with things & it's not like we don't have anything in common. Like we just never seem to have good heartfelt conversations anymore almost as if we have nothing to talk about at all because we know one another so well already. I just get bored sometimes just sitting there with him, even when we go on dates & stuff we have a hard time finding new things to talk about. It makes me wonder if I really want to spend my life with someone who gets kind of boing to talk to? Sometimes I just feel like I'm talking to a wall & he's a bobble head & nods at everything I say. Advice?
