Hi mg88,
I am a mother who has done shared custody in different time/ways over the years. I have two young adult children and a 9 year old. I am also trying to work out ways to adjust and cope with the situation. I have to move away from my child (costs of living, no suitable work hours, got evicted) so what I have done is look for community groups I can join to make friends and give me something to get up to go to when we move locations which is more hours away from my child. I look at study I can do on campus to also network and feel a part of something. I cannot change what has happened but I know now my child is ok where she lives I definitely made sure of that. He can provide an enviroment that suits her and he can work jobs that work around her. In my last locations I didn't have the same opportunities as he has. I am unemployed atm, in the past I was working all the time, crazy hours, it wasn't good even though the pay was) then we had to move and I had a MH episode.
Regarding connections I call her each week and she is often busy (gaming, friends, park) I don't take it personally if she wants to hang up to go do her thing. I have her on school holidays she leaves tomorrow. Messenger has games that you can play together and bond also of that is a thing you could try. I was lucky that my ex decided that family court wasn't necessary if I am doing things to help my mental health and have support, so we agreed on school holidays with me as it works while I can't work for a few months.
I understand the difficulties and feeling isolated. Not many mothers decide to hand over majority custody but I have to stay healthy so I am able to chat and see them. So it's difficult to find others in my situation. There are a few Dads groups around try to find a positive one that helps you accept the situation as it is so you're not too hard on yourself.
We watch a movie a night with popcorn as our thing the past two weeks. Personally, I have sought help with medication, sleeping and how to prevent another breakdown. Sharing here is a great step. I talk to her about school: teachers, upcoming camp, her new friends and being upbeat about what she is doing in her life in her new town.
I hope things begin to be more positive for you. Are there hobby groups you could try like mens shed?
