I have DS 14 and 17 who live with me. When we told them we were splitting up we told them that they can see their dad whenever they want (although he lives about 40 mins away so they can't just pop round).
STBXH partly moved out in June and then we both moved to new homes last month. Youngest has seen his dad once since then for a couple of hours, eldest has seen him twice for a bit longer. Is that normal? I don't want to force them to spend time with him but it feels like they're going to end up not really knowing each other. They don't mention him generally but haven't said anything bad about him (he lied and cheated, but we haven't told them that).
I was having a bit of a laugh with my youngest last night and suddenly realised how lucky I was, I can't imagine not having them around.
