Help me so stressed !!

Ok so I’m pregnant right now and I called my ex yesterday to tell him I’m pregnant we don’t get along anymore there’s ups and downs but when I told him I was pregnant he’s said “grand” and blocked me on social media I was very upset crying last night , I called him this morning and I said to him I don’t care if you don’t want a relationship anymore with me but don’t neglect our child I also said you have to be there as a father for our child I said you will have to pay child support for our baby and he said “hardly” which mean no

He even told me that there should be some type of medicine I can take to get rid of the baby

Was in tears as I type this I’m stressed,fed up, and my heart is broken

He planned this pregnancy with me like why is he acting like this ???

Guys help me what should I do ???
