It's hard being Married to someone with a kid!!

It's not the child it's the Child mom... I been with my husband for three Yr and the whole three years it's been nothing but problems from her...she all because he move on nd she's still not over him... He loves his child so she's mad he don't want nothing to do with her. he has a restraining order on her because of the adolescence behavior she's displayed... so its a been arrangement that they both pick up nd drop off at the police station. I'm just over the i been through to much last Yr We lost our baby boy and I had a miscarriage in April nd it still a battle with her I'm losing my mind I feel like leaving Him cuz it's so stressful ... I'm so done with this Wat should i do ladies need some encouragement before I make lose my mind!😧😧
