How do I know if my boyfriend really loves or cares for me or is just infatuated?

We met two weeks before he left for Iraq, but talk everyday. He says that I am exactly what he's been looking for all of his life. When he was on furlough we were together 24/7. His parents live near me and love me. He says his mom is a good judge of character. I am a widow and have a daughter and i worry this will change the way he feels. Although he says he is very excited to meet her. I have also promised to wait for him. It's been 5 months and he'll be gone for 9 more, but gets to come home in Feb. He's really great and I love him alot. What do you think?
