My eldests dad is forever stating he cant afford the CM that the CMS has set up. At the beginning 2 years ago never had a problem. A year ago he met a woman & within 7 weeks of meeting he moved her & her 2 kids in. Thats when he first started saying he couldn't afford the amount set by CMS. 5 months later he tried again because they announced they were having a baby. Since the baby's birth he is constantly stating to me he cant afford the set amount & would I mind it being reduced. I have refused because he recently went to Disney land for a week with his partner & her kids (my child wasn't invited) & he proposed. My point is if he can afford extravagant holidays & engagement rings, he can afford his CM payments. When I mentioned this he called me a gold digging, jealous & bitter ex because hes moving on with his life (i left him for good reasons). For our child's birthday in August he sent £10 & the Christmas before our child recieved nothing from him or his family but posted on social media a tree surrounded by gifts for his partner & her children. He earns good money & owns his house so doesn't have to worry about rent. He's also started making excuses to not have our child on the days we set out. Every other weekend & half the holidays. When he went to Disney land his excuse for not having our child was he had broke his foot. Our child was extremely upset when they found out that not only had their dad lied about his injury but also because their dad had always promised to take him to disneyland but went without them.
Am I wrong to be angry about this situation?
