Cheating during pregnancy

Hi all,

I recently found out my partner has cheated on me while 10 weeks pregnant. This was a planned pregnancy.

He has also cheated 4 times in the past but has gone to therapy about it. He blames me and our “bad” relationship for the cheating. He also lied to my face when I suspected something was going on, and only found out when I got access to his Facebook account. He met her during work hours.

I’m not sure what to do! My whole family hate him for this, I believe his family enable this behaviour. I have two older boys from a previous relationship and was single for a lot of that time so I know what it’s like to be a single parent. I am terrified of being a single parent again, and I voiced that to my partner.

He is still staying with and speaking to this person.

Any advice because I am lost!
