Advice!

Hi, I’ve just found out I’m pregnant about 4 weeks 6 days and me and my partner only been together 4 months but I’ve known him years. He had an addiction to cocaine before I got with him he’s told me he’s been clean for 8 months I believed him until recently.

He’s been going toilet a lot an constantly sniffing. I’ve gone to my desk and he had his stuff on it I moved his stuff out of way and a bag of cocaine fell out. His family thinks he’s clean as well. I just don’t know what to do or how to feel emotions all over.

Edit- we both have kids from past relationships.

It’s not only just start him saying he’s clean and going toilet an constantly sniffing.

Also only found out I was pregnant yesterday.
