Sex opinion

Roree
Ok everyone I need to opinions!!! 
My boyfriend and I have been together for 3 years, we have a 2 year old and we kinda took a break but were working on our relationship now. He told me he doesn't want to have sex till we're married because he thinks that is the best thing? What would you do? Now he won't have sex with me and it's been weeks. I really just don't have a good feeling about this.
