6 week old baby found out husband cheating

[Mumbroken]

I'm heartbroken.
My baby is 6 weeks old and I found out my husband has cheated on my several times. I'm worried about my baby and I. I want him out of the house but how am.I going to cope alone? Ive got no family close by to help. I'm breastfeeding, will this affect my supply ?
Does anyone have any legal advice?
Ive got proof. I used to volunteer for the samaritans and one of the dates he cheated i was on a night shift- volunteering ! Im so heartbroken. Never suspected it. He's been so nice and innocent always.
Also caught him watching porn and masturbating whilist seating next to our baby. Im shocked.
I havent confronted him because i want legal advice before i do. Not sure if im going to last the weekend without confronting him. Help

I'm so sorry OP. Maybe think about seeing your GP/HV on Monday and reporting the safeguarding concerns as well as the cheating. Tell them you will not leave your baby in his care at all. Feign illness/upset tummy over the weekend to keep him away from you. Take baby to go stay with your parents as soon as you have the passport. Tell him you're going for a week, but stay as long as you want. When you're both safely out of the way, text him and his parents that you know what he's done and have proof and tell him to move out.

I know this is horrific timing but a year from now you will be so glad to have this duplicitous cunt out of your life.
