fwb with ex

me and my girlfriend of almost two years broke up recently for a few different reasons but we decided we were going to try again in a few months, to a few years. anyways we decided to be friends with benefits because we’re still in love with each other and the sex was bomb as fuck. but i’m kind of scared doing this is going to ruin our chances of getting back together in the future, but at the same time i feel like it could help us still have a chance to get back together yk..?
