ex wants to be fck buddies

we broke up a year ago and were together for 2.5 years. he wants to have sex whenever we are horny.. but doesn’t want anything more. i definitely could marry him and want to have his freaking babies but should i just settle for fuck buddies? or is that not smart of me for potential emotional attachment issues? hmmm 🤔🤔 has anyone ever hooked up w an ex? if so how’d it go??
