He said "I love you" way too soon, how should I react?

Hi guys. I met a guy on Facebook approximately 1 month and 1 week ago. We immediately began texting and one night, we spent 3 hours on the phone. I can safely say I felt the chemistry. It’s been a month and we do plan on dating when we see each other. He’s currently out of state but he plans on coming to see me over the Christmas holidays and he’s moving back to state from then.
What confuses me is we never met, however, he has given me money, always willing to buy things for me, and he said recently that he loves me! He says he’s been hurt in yh4 past before by his ex girlfriends and since he’s had some low self esteem problems.
I had guys in the past tell me they love me after 2 to 3 months but never 1 month.
Should I be worried or go with the flow? Plus I never know what to say when he says he loves me.

PS. I’m 21, he’s 20.
Thanks.
