Don’t know what to name this topic

I’m 35 weeks and 2 days with my second baby and first baby girl. I have a two year old baby boy. I am very excited and happy to meet my baby girl but at the same time im so heartbroken because I found out today that my husband is cheating on me with my best friend and he is doing drugs. I feel like im standing in the middle of the ocean on a small island and have no idea what to do or where to go. I am not worried for myself but i am so worried about my babies. I am so sorry for this topic but I thought I might feel better if I share with someone and I didn’t have anyone to share with other than all of you ladies here. I am so sorry 😭
