Ex texted during quarantine

my ex broke up with me 10 months ago . He hasn’t bothered to message once or even ask if I ever been ok since . 3 days ago he decided to message hello.

Our breakup was really messy .Although I was more upset and sad . He was just a complete asshole .

Instead of an apology or a legitime conversation starter he decides to text hello .

Mind u , I know the guy has been completely isolated 100% doesn’t have any friends or family since we broke up . He lost his job and hobbies due to covid19 .

So he’s been isolated , alone and jobless for weeks now .

I was going to never message him back but it felt good that I have moved on or in the process of and hope he moves on too . It felt good to let go of all anger and bitterness . But there’s a hole growing inside of me that’s making me feel really bad and harsh ... Why do I feel so horrible ? About it ? I love the guy but it’s a different kind of love for sure now . I don’t miss him anymore .. but why do I feel so guilty that he doesn’t have anybody .. else
