Split with my ex 3 years ago. Our child was 18 months old. He works shifts so contact was sporadic. He does/did maybe 1 out of 5 weekends and a night or 2 a week. Our child is due to start school and all of a sudden he wants every other weekend ie Saturday am to Monday pm and he's changing his working hours. He's being enthusiastic at present saying he wants more weekends off etc. Why after leaving the majority to me for 3 years ?
