On his last weekend he and ow took dd to the beach. Ageed time to be bsck was 7 due to school even tho he asked for 8(pm). I got a text at half 7 supposedly sent much earlier saying they would not be back til 8. Now this weekend agreed time back is 4pm. Just got a text asking ifit xan be later as he and ow have taken dd camping approx 270 miles away amd they would like more time on the beach tomorrow. I want to say no. Am I being a bad kom to say no?
