My ex-wife keeps undermining me
I believe I'm a fair father. I don't ask my 2 sons 11 and 12 yrs old to do anything they cannot handle, but when they misbehave or lose their sense of responsibility I end up having to raise my voice. Last school yr, I accidentally found out the my 11 yr old missed 3 reports. Since the day I found out I was on him about doing the missed assignments. I guess my ex-wife got word from the teacher that he already received a zero so my ex tells my sons he doesn't have to do the assignments. My point was that I have him do the reports and have him understand the importance of completing his work, BUt she says" Damian you don't have to do it."
Another one is that the boys don't like it when i raise my voice and I only do it after i've told them several times of what was needed to be done or to stop what they were doing. I am guessing that she told them "if your father yells at you then call me and i will come pick you up."
I love being with my children, every minute I have with them I cherish. The problem is she does not respect my privacy. I've tried to explain that I have different rules at my place from her place, but she makes everything worse than what it is.
What can I do? Someone please give me some advise. She is making me look like the bad guy
