"I love you."

I feel like I say "I love you" too much to my fiancé. 
and I know people associate that with: "you don't really love him you're just saying that".
I really do love him so much and I think it has to do with my borderline because I'm so afraid he'll leave and I don't want him to ever forget that I love him. 
what do you think? am I overreacting or do I need to change my weird habit? are there any tips??
