Don't hurt yourself! I was a self harmer for 8years and as soon as I fell pregnant I stopped because its so harmful for baby.
I suggest you leave him and go stay with a friend or family. Then maybe talk to someone about your feelings. You have a baby to care for, so you need to worry about him/her only now.
Sorry that your husband was cheating.
You either work on fixing your marriage or leave him.
My (soon to be ex) Husband bailed 17 weeks into my pregnancy and cheated but came back and wanted to be a family when she was a week old.
I tried for 5 months to make it work but Daughter and I were happier on our own.
He doesn't want **** to do with her now but neither of us are missing out :-)
She's two now and my boyfriend of 16 months has been the best daddy to her and we're expecting a baby together in February.
Dont do anything bc its not worth it. i had a suicude attempt in september last yr and fpund out 3 months later i was expecting. now i couldnt be any happier. just work thru it and tlk to ur doc to get some help.
