Me and my ex husband had an extremely acrimonious divorce. Following the end of the court process I wanted a fresh start and I've decided to change my phone number as part of it all. We have an 8 Yr old child together so we both still need to communicate. We use a co-parenting app to communicate mostly. AIBU in not providing him with my new number? Also does anyone know of any apps that I can use that gives me a second phone line number (if I did need to give him my number) ?
