Scared of loving my boyfriend too much?

I (22F) have been dating my boyfriend (24M) for a little over a year, and I love him a lot. The curious thing is that the longer we’ve been dating, the more I love him. Throughout the relationship, he has done things that made me obsessed with him (showing vulnerability, gentleness, etc.). I feel like I love him so much that it sometimes feels a little overwhelming, and it scares me that I might be too intense for him.

He is a very tranquil guy, really smart and simple. The whole thing surprises me because I’m not usually a very intense person. In fact, everyone around me sees me as quite a cold person, so the effect he has on me is almost a miracle.

All of this comes with a feeling of fear that things might not go well, that he might not reciprocate these feelings, or just that life could get in the way and things might not work out in the end. I feel like that would destroy me
I don’t know how to get rid of this fear or how to talk to him about these feelings that I’ve been keeping to myself.
