When a suicidal person you should do everything except: a. explain that their problems are temporary b. actively listen to them c. show your support and love without judging them d. earn their trust by keeping any and all secrets

Personally I feel all apply. They need all of these and a true friend and thats what you should be. But its only an opinion but a strong one.

the are no statements

if your boyfriend is cheating on you, my best advice to you is to dump him, he's only going to drag you down. and if you do, don't fret there's plenty better that know how to treat a person right. i mean honestly, the whole point of a romantic relationship is love, and if you love someone you aren't going to cheat on them. i do believe in second chances, but why would he cheat in the first place? i personally feel that if someone cheats, they ruin any chance they wanted/had with you. i wish you the best of luck with this, hang in there.
