I'm coming to the end of a divorce and it's becoming apparent that 50/50 isn't working anymore. Ds is going to his dad's house and being constantly left with his nan while his dad goes out with friends the gym etc etc. Ds has told me on a couple of occasions now that he is sad and lonely because his dad isn't there and I have no idea what to do. His dad demanded 50/50 even though he was hardly around before we split up as he was always out with friends or his hobbies and this was initially working for ds but exh is reverting back to his old ways and I know he only wanted 50/50 to hurt me not because he loves his son. Exh was emotionally abusive to me through out the relationship. Anyway how do I go about getting this changed in the best interests of ds, do I need to speak to the solicitors. Any advice would be much appreciated.
