I feel like I can't trust men anymore

in the past week I've been stood up/played 3 times. all I want is a fucking relationship and I don't get why everyone feels the need to play games. 2 different guys fucked me over- one talked to me all day every day, took me on a date, made plans for our second and then blocked and ghosted me the day before because he "was having issues with his ex" and the second guy calls me every night for 2 hours, made plans with me a week ago and they fell through, and then made plans again today for this afternoon and just cancelled on me after I did my nails, hair, outfit, etc. I'm so sick of being led on only for this shit to happen. I try to be so sweet to the guys I talk to and I never hurt anyone or ghost/block anyone and this is what I get. what's the point of making fucking plans in the first place if you don't want to (all 3 times it was the guy that initiated them, not me). I'm so fucking done and I never want to date again. I'm 21 and it only gets worse every year. I was in a relationship 15-20 and I haven't been able to get in one since even though I'm completely over my ex. every time I talk to a guy I feel like I'm just waiting for him to leave. even when they seem amazing they end up doing shit like this.
