I need advice: UPDATE

Ashlynn • 12 years old.

I got these messages from some random girl yesterday. Let me just say I bawled like a baby. My husband and I got married at the end of April. This girl says they slept with each other in the beginning of April. All his friends plus one of mine says he didnt. They were always with him. He has this crazy ex, and she just wont leave us alone. But I dont know what to believe. My husband says he didnt. We also began moving into our apartment around that time. I'm so heartbroken and lost. I dont know what to believe. Any advice on what I should do? Also, I found out that the number they used is a Textnow app.

Update: found out it was his ex. She would not respond to me. Even after I asked for her name and proof. My husband said it was a lie and everything. I really hate that women can be so mean to each other that this can be a result. Thank you ladies for giving me advice!
