I’m tired

My friend owes me a lot of money. I’m thinking of suing him. Mainly because of this. He stopped paying me and bought an AR15 instead. He said he was selling some property and then paying me then played dumb until today when I asked him about it and he says the people buying backed out. I think he’s taking advantage of me. I think he is only acting this way because he doesn’t respect me and thinks he can do whatever with me. There’s a couple problems here. For ones I no longer believe anything he says. Two his priorities are not me. He is just a POS. I think it’s time he owes someone else the money. Someone who he will respect and pay back. Someone who he will be like all I got is ten dollars but here you go. You know? I am THAT reasonable. I know he going through a hard time, but it feels like he doesn’t care anymore. Like he just want to leave it at is but it’s too much money for me to let it go.
