8 months pregnant and just found out husband is cheating.

Never thought this would be me. Please help me know what I’m supposed to do. I just found out that my husband of five years is texting and meeting up with an 18 year old girl. They haven’t full on cheated but they’ve done everything but.

I have an amazing almost three year old and I’m due with baby two next month.

I’ve struggled with my mental health my whole life and have admitted myself to the psych ward several times over the past six years. I’m so afraid if I try to divorce him he’ll use the to prove I’m an unfit mother. Even tho I am an amazing mom. I can’t say a lot for me but I know I’m a good mom. He spend next to no time with her and rarely helps out.

What do I do?? I don’t even know where to start.
