Tbh I think it's more possible to have the opposite effect, stopping the pill means you will have to adjust to being off it and the change in hormones can result in side effects, possibly including mood swings/emotional changes. So personally I wouldn't want to add that on top of going through a breakup, but if you don't like being on the pill, it's of course up to you. When you stop, make sure you have condoms around as contraception because you never know when you may become sexually active again.
