Is it normal to be with someone you love but doesn't give you what you need?

Is love enough? There's always these statements that say love isn't enough, or if they're not giving you what you need from a relationship then find someone who does. Well what if you're just staying cause that person just makes you happy? and you're willing to settle for whatever they give you cause apparently, love is enough for you? It's like you rather be with someone you love through thick and thin than with someone you aren't really crazy about but treats you right? Its not that simple when they say "why are you with someone you don't trust?" "why are you with them if you feel like they don't feel the same you do?" If those questions were applied towards my relationship with someone I just like then yeah those questions would make me turn the other way. But in my case right now, those questions aren't enough for me to just walk away from my bf. It's not that easy. He makes me happy with just a thought of him, with just his presence, with just his personality, etc. He doesn't treat me badly but he can def treat me better. I don't fully trust him...well why am I with him? cause of how I feel about him. He's not always attentive with me...well then why am I with him? same answer. I just can't see myself being satisfied with someone else like I am with him. It's like my ex for example, yeah he treated me right and everything but i never really loved him. I didn't feel satisfied. Just cause he treated me right, doesn't mean I shouldve stayed with him forever. It wasn't fair to both of us. With my bf as of now, I do feel satisfied with him as a person than with my relationship with him. Is it possible and okay to be with someone in this situation? I just feel like later once we get settled down, our relationship would be more of a priority.
