Should I wait or let go?

So I started working at this place back in September of 2010 and met a girl who was about 3 years younger than me. We hit it off from the first time we said hello. We started talking a little (she had just come out of a 3 year relationship) and we went out several times and just had a blast. then all of a sudden she says she not ready to be in a relationship so I was like thats cool Ill just give her some time. About 3 months later she starts wanting to hang out again and tells me than she is attending a church thing for a year that will not allow her to date or be in a relationship for that first year. I was still getting some mixed signals at this point but one morning of the blue I decided to text her and just tell her to have a great day and I was thinking about her. She responds and tells me she loves me with her whole heart and that she doesnt want to go a day without me in her life. We go to lunch the next week and I asked her about the text and she says she was just speaking from the heart. I was leaving for the beach 3 days later and Its like she would not let go of me, we talked constantly for two weeks and then I didnt talk to her for 2 days...she wuldnt return my calls and eventually she calls me back and says she needs me to wait. So I told her I understood, its just been a rollercoaster ride and Ive been praying about it constantly...I just dont know if its worth the wait, I mean I can tell she loves me deep down but she dosent want to get in a relationship for 2 months and then have to take a 12 month break and end up getting to attached and not being able to focus on her church thing. We went and hung out a little the other night for like 2 hours and I basically told her the way I felt and how hard it was gonna be to let go for a year. She told me for the third time that she loves me and it was probably the most sincere of all. She says she just needs me to focus on my things and If it is in gods plan it will happen. I guess im afraid of waiting a year and things change and we dont every give each other another chance. However, I know it takes a lot for a woman to say those three words. Just dont want to waste a year of my life but I dont want to miss out on something special either that we have between us. Its just every time im with this girl I have a harder time letting go. I just dont know what is best and would appreciate some opinions.
