Love.

So I know I love the guy I'm with, and I know that I want a future with him. But with every guy I've been with I've lost interest in the last 8 months. We are at 8 months and a week. No matter what I love seeing him even when we are arguing or he's irrating me. I'm just scared something is going to change the way he look at me. Because I've fallen in love with this guy. And everyone knows how happy I am. Also when I get close I push away afraid of being hurt again, and he isn't that type of guy at all.

Am I over thinking it? Or is this normal?
