I let my ex visit when he wants on the weekend. He is a functioning alcoholic so we haven’t seen him recently but I always keep the option open so he can see them. There have been a couple of instances where he has taken the odd days off during the week then asked to see them. ITs basically when things haven’t worked out with a date or something. My friend says I shouldn’t make myself so available as we seem to be second choice if a date doesn’t work out, but I just want the kids to see him as much as they can. Am I being a mug? He isn’t the most reliable as drink has really taken over his life so when he does drink, I know we won’t see him. So I take what I can get.
