I’m not in contact with my ex and he doesn’t see our children, we split up almost 5 years ago and since then he has barely seen our children (he’s seen them on about 3/4 occasions in that time) the last time he saw our children was over a year ago, in that time he has not asked to see or speak to them. I am planning to change my number (I have reasons for this) but have been told it’s my duty to inform him of this, I don’t plan to contact him and I’m not comfortable with doing that, the last time we spoke he made it clear he wasn’t interested in being a dad or seeing them so I don’t plan to chase him. Apparently though it’s up to ME to prove I didn’t make it difficult for him or didn’t try to stop him, why is it up to me to make sure of that? Surely it’s his job to prove he did try? I don’t plan on having contact with him again and if he wants to see the children again at any point in the future I would want this to be through the official channels anyway so he can prove he is serious and won’t be letting them down again like he has done over and over. So he has my address and can get in contact that way. Am I wrong for thinking it isn’t my job to prove he didn’t try? FWIW I do have messages where he’s said he won’t be seeing them etc
