My exes won’t move on and it’s bad

Both my exes are "obsessed" with me and I am scared

This isn’t a humble bragging ass post , I’m not even all that , just a random ass 20 almost 21 year old girl and these people are somehow very attached to me and won’t move on. I also have moral ocd and anxiety so I feel so much guilt about this like everything is my fault.

First ex we dated when I was 14 for a year and then we reconnected years later and apparently while we were broken up based on his account and like 3 other people he didn’t stfu about how much he loved me and so on. My second ex we dated during the Time I was broken up with my first ex so at 16’and then we broke up and he came professing his undying love to me 3 years later while he had a girlfriend , oh and of course , he had to tell me how he developed alcoholism and drug abuse because of the breakup , oh and posts about me and drunk calling my friend multiple times to tell her that he misses me , and contacting my 12 YEAR OLD BROTHER one time AND called me his god or whatever. I , of course , told him to move on and love his girlfriend who actually loves him so don’t come for me. I did not cheat with this guy.

I got back with my first ex at some point because 18 year olds are stupid and just be doing shit and after emotionally abusing me during the relationship I literally was crying every other day he broke up with me because I was asking for so much and it was stressful , I had a breakdown myself , I went to therapy , got better. Guess what ? He’s talking about how he would never let me go , I’m the only person he could ever be attracted to and how he won’t give up on me and how he would commit suicide if I was with someone else. I still love him too but I want to move on because I was treated horribly.

How can I be responsible for ruining this many peoples mental health ? How come every person I date just collapses after the breakup. Why does this have to happen , I don’t wanna be responsible for
This stuff. I am literally a random in every sense of the word omg. And I would maybe understand if I was good in bed or something , I NEVER HAD SEX WITH EITHER OF THEM. AT ALL. My second ex cheated on his gf so I don’t feel that bad for him but I really feel bad for my first ex and want better for him.
