Long story short my children's partner left us on the day I found out I was pregnant with my second, after trying for months. Over three years on and he is still not consistent in their lives. I find myself begging and forcing him to have the children which is so upsetting he doesn't want to play an active role in their lives. He makes promises that he will see them more and then suddenly he has a work emergency or not enough money or he's too stressed and he won't see them for months on end. He has seen them for three days over the summer holidays and I've had to tell him I am bringing them to him for a weekend and he's been horrible about it which is another thing. He is so nasty to me like he actually hates me and whenever I ask him nicely to have the kids it turns into a personal attack on me and my parenting. I love my children to pieces and it's breaking my heart knowing that he puts in zero effort and I always have to make excuses for him as to why they haven't seen him. I'm getting really fed up of his constant negativity and unwillingness to support the children. Now I'm wondering if there is any sort of professional route I can take that can get some sort of routine set up legally so he has to see them more? I get a little support from my family but I would just love them to spend more time with him as I could never fault him as a father before we broke up he just can't be bothered with them because of his personal feelings towards me which I always tell him shouldn't matter at all what he thinks of me it's about them at the end of the day and it's boring listening to his hurtful comments all the time when I am asking a simple question as to why he won't see them more. I would really love and appreciate some advice on this matter because I find myself feeling guilty for not being able to persuade him and I don't want to give up on them having a dad but at the moment they really don't have one anyway.
