So I have been dating a very wonderful man for about 2 months. He has two children who are 19 and 15 Officially they live with their mother and her partner but understandably they visit my bf when they please. The problem I have is that as much as I like him I am finding it really difficult as he won’t make firm plans between Thursday and Sunday evening in case his children decide to come over either together or separately for the weekend . He says he cannot go out. On one weekend the children were going out on their own on Saturday and he suggested meeting but would only confirm meeting me once they had physically left as he said he did not know when they would go. I find it really uncomfortable as he frames it as spending time with his children whereas I see it as managing time so they get to spend time together as a father and children unit and nurturing a relationship which he says he really wants. In two months we have not spent a whole day together. I think it’s a really good quality he is such an invested father, however I can’t see why he cannot tell his children he is spending Friday evening or Saturday evening with me now and then.he says it will change when school/university resumes but I can’t really see how it will as the key factor is the weekends when certainly the younger child can visit . I’m not sure what to do.
