My husband left me for an 18 year old girl after my birthday, what do I do?

I just found out my husband has been cheating/having an affair with an 18 year old girl he met online.

I feel completely heartbroken and don’t know what to do. We built a life together. I feel utterly crushed and broken.

I don’t know what to do.

After this we broke up recently and separated ways. I do not know what to do now. We are talking about divorce.

He left me for an 18 year old girl. I feel broken. I am only 27 and attractive, beautiful, pretty, slim in great shape, etc. My husband is 36. I thought our love was solid but I guess I was wrong.

I’ve been drinking for the past few days, sleeping and smoking.

I don’t know how to move on from my life when I believed he was “The One”....................... I don’t know what to do. How can I move on or get over this? Is there a way to get him back? Is this a phase with him ? I’ve been freaking out and crying.
