Boyfriends mom competing with me?

Anonymous
This is kind of a weird situation I'm in and I would like some advice in how to handle it please. My guy and I have been dating about 2.5 years now we are both in our mid twenties and we live together in a cute little apartment. Every time we go to his mom's for dinner which is just about every Sunday and I happen to mention to her a new food I'm going to they to cook for Ben or something like that the next time we are over she has the same exact food I was describing prepared. Or like on his day I was making conversation with his mom when he left for a fire call and I was trying to bond with her and I mentioned that I was going to make him a bday cake this year since I never done it before. Low and behold when we go over for his bday she has the same friggin type of cake to a T prepared. She did the same thinf last year with Christmas gifts I mentioned I was going to get him a nice new wallet and then well you guessed it she went out and bought it for him. I think she is a little jealous that I am starting to become to main women in his life and Im aware I probably sound paranoid and crazy when I say that to you guys. I swear though its just about every time I mention something I'm going to do for him or buy for him that this happens. I know that the easy solution is to stop telling her but I don't want it to have to come down to that because she is really sweet in all other areas. Obviously my bf is definitely a topic that we both have in common Lol because we both love him equally. Differently obviously but equally. What do I do? I feel like I'm going to hold back my resentment so long that one day I may explode and I will end up saying something I regret.
