Broke up and i have suicidal thoughts .. HELP

I broke up with my boyfriend few days back, he never keeps his words, he has been telling me how we wants to marry me but never took a step. He always does fake promises and never keeps any. He is manipulative and a liar.

I wish I could post more details but for now im not in that state.

He have been trying to talk to me like we are friends or something

But I just can’t.
