Sleeping with an ex

My ex and I broke up to focus on our personal issues and our life goals. We dated for a year and we so emotionally connected, we went threw quite a lot in the past year. He’s honestly one of my best friends. But I’m really trying to focus on myself and better me, but I have needs lol so I booty called my ex and we’ve been banging like rabbits all week every night since. And the sex is almost better than when we were together! I reached out to him because sex is just sex and we are safe sex and comfortable and no point in rando hookups because I’m not into that and I don’t want to sleep with anyone serious while I still have a lot of work to do for me..

what are your thoughts and personal experiences with sleeping with an ex??
