does any1 else think that reid might be in 사랑 with JJ??

Of course not. Although that sounds like a crazy 팬 fiction i read once. But i think they weren't compatible so they stayed friends.
and he was probably just proud of her bec the baby showed how she is getting her life together and a new life would 가입하기 her. And he was probably happy for her as a friend who is helping the human race survive. ;D

Ok I lok up alot of Spencer tied things and it's said Reid dose have a crush on jj 

he is he is in (love) with jj and prentiss he asked both of them on a date

I think he has a crush on her, yes. I have since the first episode I watched, and I don't like them together at all.
