My Fiancee and His Ex! Please Help!!!!!!!!!!!!!?

Okay I just want to know if I'm being retarded or if it is something that is just a little unfair. My fiancee and I have a 9 month old son together. He has an ex named Jess and they dated and broke up about 10 years ago and they stayed friends after that he's even the godfather of her daughter. Well the 4 years that we have been together during Christmas he had never bought anything for his ex for Christmas. Well this Christmas he did, he bought her bath and body stuff a whole basket full. He was going to buy me a new camera for Christmas, but he didn't because they are just SO EXPENSIVE (well any of the good ones) so he doesn't know what he is getting me now. Part of the reason it bothers me is because he was the first person I got done for xmas shopping and he hasn't even got me done yet, because our son was the second one we got done for shopping and he gets his ex christmas presents before me. Another part of it is because I know for a FACT that his ex still loves him. His ex isn't a ***** or anything I get along with her just fine and she doesn't interfere. So it's like "why are you buying your ex stuff when you haven't even gotten me anything yet?" Please help me!!!!!!!!!!!!!!!
