Should I tel him I love him?

Okay so this is going to sound very silly

But I’ve been ‘officially’ dating my partner for 3 months now. Due to it being long distance we have known each other for a couple years now after meeting at a party I was at with my partner at the time around 2017. We began talking daily at the beginning of the year and I quickly caught feelings for him and he did for me aswel. He was a very good friend and he helped me through some horrible times in life. We have finally started dating long distance and he has openly expressed the desire for me to move in with him in the future which I look forward to

I really love this man. And I want to be able to tell him I do as expressing love is very hard for both of us and is a serious matter.

Should I tell him I love him or is it too soon? And how should I tell him. I’ve never had a man treat me this well before
