Sometimes I feel like I was more secure with myself prior to being in a relationship. Is that normal to feel?

My boyfriend is nice to me, but sometimes I just feel like he doesn’t care. We’re long distance so that’s pretty difficult in itself.

I don’t know what to think. I just know that I make him feel way more secure than how he makes me feel. The efforts seem unbalanced. He doesn’t compliment me much and when he does, he once said: “I am so attracted to how you find me attractive”. Has anyone else felt insecure in a relationship before? Any advice or kind words would help.
