How can you tell when someone is obsessed with you????

I've been seeing this wonderful guy since my split but I'm startin to think he's obsessed with me. He has everything a woman could want, he's a great guy but I'm starting to think it's going a bit far, maybe I'm wrong you tell me. He says he luvs me w/ all his heart, he will give me anything to make me happy, he would give everything up if I just open myself up to him, I didn't answer his text messages one nite cause I was in cl (we are adults) he showed up in the parking lot of my school so when I walked out there I was freaked out to see him there. He said he need to talk to me so bad. He says he prays day & nite for God to give me to him. I'm fresh out of a divorce so I'm honest w/ him & tell him I'm not ready to commit yet. He says he understands but I don't think he does. I went to talk to my ex on sunday & my guy friend said he went to church while I was there & prayed. And he wants to spend every moment together..is this getting to extreme or am I taking things wrong??
