Hi everyone, I am new here and don't really know how this all works so forgive me if I am not doing this correctly

I have been seeing someone for about 6 weeks now (long distance) and last weekend he told me he is not sure I am the one - and he is having doubts - I have some doubts myself but haven't said anything because I just think it is too soon to know and I was going to take some more time to decide - I am just wondering do you agree? He came on so strong and i have been letting him take the lead - and he has up to this point - he has been awesome, but now??? he is talking to his counselor this evening and will decide if he wants to continue to see if things change or if we will no longer be together...just wondering what other people think of this situation - if you don't feel that "spark" as he calls it now are we doomed? (and yet he really likes me, there is definitely attraction there, he says we have a great connection and he loves spending time with me??? so do you think he is just scared??? ) or do you think we just need more time to find out? I am a bit freaked out today and could really use some advice - thanks
