Pixie, I think it depends on how long you've been with him, are you still "falling in love" but mostly, does this feeling interfere with your normal day to day life. Do you sit and pine over him or is it an "I can't wait to be with him!" kinda thing?
Do you have to ask him his opinion every time you need to make a decision or can you go ahead and make a decision for yourself?
There's an awful lot to consider!
