I apologise in advance if this ends up being a long one.
I have been separated from H for 7 years. I could not continue to live with him as he is chaotic, messy, irresponsible and we clash like wolves. However, for the past 7 years I have maintained some sort of relationship with him for the sake of our DS (13). H lives in his brother's house in a town that is one hour away from me. He has never been able to provide a home/room for DS.
For the last 7 years, he has visited DS here at my home. On weekends, sometimes during the week - he has stayed on our sofa, eaten family dinners with us, walked out shared dogs. My home is close to his work.
I have never wanted to be back in a 'proper' marriage with him but we have muddled along as a family unit.
At the start of the summer he suddenly went weird on me - not answering his phone, ignoring messages. He then cut all contact with me and didn't see DS for 11 weeks. He just kept saying - oh he's a teenager now, he wants to be with his friends at the weekends. The only way I can contact him now is via his brother. I have to text every week to ask for my maintenance money.
I have subsequently found out last week that he has got a new girlfriend from round about the point he went funny on us. I don't care about the girlfriend. Or maybe I do? But I'm fuming that he has ditched DS. I feel like he used us for 7 years until he managed to find someone else.
My feelings are wild. I don't know if it's anger, jealousy, grief, or everything mixed together. Why couldn't he be decent? Why didn't he divorce me if he wanted to start a new relationship? How can he just not bother with his son? It doesn't help that since he's not been around DS has had some quite serious behavioural issues. I asked him on Monday to take him for a few days as I needed a break. He has now dumped him at his brother, who is caring for him.
It's all such a mess and my head is spiralling and I don't know how to deal with it all.
