[TOMT][MUSIC VIDEO][Late 2000s] Obscure R&B group video about cheating, ends with woman/couple dying, woman wears a yellow dress

I've been trying to track down an R&B music video from the late 2000s (or maybe early 2010s). Here is everything I can remember: The Artist: It is an obscure/lesser-known group (not a solo act, and not mainstream pop stars). There is a female singer, and they might be Latino. The Lyrics/Title: The lyrics definitely have something to do with "your love is like a gun" or "shoot me down with your gun." The word "Gun" might even be in the title. The Video Plot: It has a gritty, gangster-style setting and involves a heavy cheating storyline. The woman finds the other girl in the couple's home? Key Visuals: The woman in the video maybe wears a bright yellow dress. The Ending: It has a tragic ending where either the woman or the couple dies with a gun? I think by her own hands after going to the new couple's house? Things I already know it is NOT: Kat Dahlia - "Gangsta" alt-J - "Breezeblocks" Ashanti - "Rain on Me" CHVRCHES - "Gun" Anything by Selena Gomez, Florence + The Machine, TLC, or Destiny's Child. Any ideas? The yellow dress and the fatal ending are the most vivid parts!
