Birth Control affecting Relationship

[wprutsman]

About a year ago, I switched to Nuvaring from the pill. When I started dating my boyfriend, whom I am still dating today, I was on the pill. I switched to the Nuvaring because I thought that it was a more reliable option for me because I would always forget to take the pill. About 5 months after starting to use Nuvaring, things began to change between us. We still love each other very much but he gets a weird feeling like he isn't supposed to be with me. I have been looking into something called Major Histocompatibility Complex or MHC. I think that it is possible that the Nuvaring has altered it. Is there anyway to know if this is the answer to our problems? Because other than that our relationship is normal and we have been unable to find any explanation as to why he would feel the way that he does.

I've read many articles that birth control can change how you smell to your partner, sounds odd but pheromones and MHC have a lot to do with how you select a mate. And I think that I have altered my pheromones and MHC due to my change in birth control. It's not so much that he feels like he shouldn't be with me but he feels like his feelings are changing. Almost losing his attraction towards me. Not that he thinks I'm ugly or anything like that but it seems like the chemical connection or "chemistry" is off.

I am just curious as to why you think that your birth control has changed your relationship, especially when you say that he gets a weird feeling like he isn't supposed to be with you? How would your birth control affect HIS thoughts like that?
