My bff bf squeezed my ass

So I was out walking with my bff and her bf who is my freind and he squeezed my ass as soon as my bff turned around he stopped so when I got home I called my freind and told her the situation she asked him in front of me and he said it was an accident how can squeezing someone’s bum be an accident he then rings me the other day and say remember the time I touched ur bum and tells me if he ever has another child he’s naming his child after me my bff and him aren’t together anymore I find this weird am I overthinking things because if he likes me in that way I should cut him off or set some boundaries as he’s ment to be one of my good freinds ps. So he’s been in jail for a week for a petty crime has written to me twice and wants me to go visit idk what to do Idk if I’m overthinking the situation or he’s just been a freind
