My ex and I have a three year old little boy together. We have separated for over a year. We both currently work full time and share weekends. I have to be flexible for my ex, as he sometimes takes on extra work in the week. I'm finding this arrangement is becoming very limiting. He either has him the preference of the night that works best for him or if I have plans on one of the nights, for the whole weekend. However, as he stays with me during the week, he won't allow me full weekends when I want, as he says he wants to see him every weekend. I have suggested we do alternative weekends, as then we both get long periods of quality time together. He does not want to agree to this. AIBU to think this is a much better agreement all round? I never get full weekends with my little boy.
