The pill

Has anyone experienced any major emotional changes when on it? Because I was considering going on the pill but my boyfriend doesn't want me to.
Obviously it's my body and if I want to go on it then he said he'll support me because it's my choice but he doesn't want me on it because apparently he knows a few people that have tried it but then the relationship has failed because it changed the girls hormones and chemistry so much that she was no longer interested in the guy. 
Basically he's scared this will happen because he doesn't want to lose me if I went on it and I was wondering if anyone has some input on the situation.
