Any advice

So Friday I went to the doctor and got a pap smear it’s hurt but i got it over with so 10 mins ago my doctor call back with the results she said everything is normal that was good then she said that I got Trichomoniasis she explains what it is but she gave me medicine while i was at the doctor for something else but this medicine will make it go away. Then she explain that my partner need to get check (really not my partner) i had to put two and two together that i got it from this person i used to talk to and we didn’t use protect right now we don’t talk do you guys think i should tell him to get check out before other girls be in the same predicament that I’m in ? And how should i tell him nicely HELP!!
