This is a situation help me?

I am a very strong willed person. I don't let men walk all over me. But for the most part I have been celebate for a year now and im learning alot about myself. I have not had a boyfriend in 2 years. I've been seeing this guy now for almost a month now. He's a really nice guy, when we go out he pays for everything and pays for my friends when they are around. He says that he respects me being celebate but I am not sure if I belive him. We have so much fun together and I get erflies when I see him. I have been in a bad relationship in the past and I don't want to go down that road with a different person, so when we do be around each other I tend to pull back or not call him for a few days. But when I don't call him for a few days he blows my phone up. But when I call he can't be reached is he playing games? I am really felling this guy, but he's divorced with 3 kids? He has money because he has a good job. I don't know someone help me!!!!!!
