A little reverse insight for you:
I was married for almost 2 decades. First decade, from when I was 18-28, it was just my ex-husband and I, we had the best life together, travel, laughter, our own businesses, freedom to do as we pleased whenever we pleased, financial bliss, and a pretty mind blowing sex life.
Second decade, when I was 27 we decided we were ready for a family and our DC was born. Ex-husband is 6 years older than me. Fast forward and we had another 2 DC, all planned and all very wanted, I was 34 and he was on the cusp of 40 and it all fell apart.
My ex-husband through his own admission but without my knowledge became more and more dis-engaged with family life. Freedom to do as we pleased became working around nap times. Mind blowing sex became an endless round of night feeds and working out sleep patterns. Travel became wherever was overtly child friendly and upon arrival we were doing the same things as parents just in a different location.
Life progressed and I was in heaven, (I was born to be a Mum as well as a kick ass and wholly independent woman!) My ex-husband bought into the fantasy of being a Dad but he was never truly content or at peace with his role as I am with mine. He missed life before children but felt completely ashamed admitting it to anyone, especially because I took to it all so naturally and even more so because he wanted children more than I did and we waited so long to have them because I wasn't ready.
He went on to be unfaithful, (I am not for one moment suggesting that this is what you have done) I found out, he stated he was in love with the OW and wanted to be with her and we split up.
Our DC were 1, 3 and 7 at the time. He moved out of the city that I still live in with our DC to a different city just 45 minutes away.
When he left, he promised me and our DC that he would see them every weekend without fail. Our eldest took it the hardest and all she could see was that her Dad had left her, no matter what was explained to her or how it was worded.
Today, almost 4 years on he now sees our 3 children once a month for 6 hours give or take. He has very little communication with them otherwise and supports them financially but does little else for them.
His reasons for this:
I need to find myself, I lost myself many years ago and I was unhappy with my life and I deserve to be happy too
I found a woman that truly unlocked me like no other ever has or ever will. I owe it to her and to me to give us a chance.
My children will always be in my life, OW has only just arrived, I need to invest in her which will ultimately benefit my children because I will be in a better frame of mind
My children will be happier if their Dad is happier
My children will understand why I am doing what I am, I will talk to them, they are strong
My ex-wife is an amazing mum, the best ever, she can handle this and she will make sure that they are all ok
I will still see them, surely the QUALITY of time is more important than the QUANTITY so even if I see them less, it will be better because I will be happier meaning they will be happier
My mental and emotional health cannot take it anymore, I need to do what is best for me and OW as well as my children but I need to be happy to make my children happy
I love my children, they are my no.1 priority, but I can't keep living like this and will need to see them less, but I love them and they are my no.1 priority.
Do you know what these statements have done to my children?
My eldest DC BELIEVES that Dad picked OW/girlfriend above all else. Said OW/girlfriend has now left him anyway.
My DC BELIEVES that Dad is a very selfish man who never truly loved DC because if he did and even if we split up, Dad would have been there no matter what, as a Dad because that's what parents do
My DC BELIEVES that Dad is not a good person because instead of being strong for DC like they see their Mum doing, they have seen Dad, now 4 years in, reduce time with them over and over again with the promise that the quality would increase because Dad would be happier, and all that has happened is the time spent with their Dad is less and the quality is just as bad if not worse.
My DC BELIEVES Dad can't be relied on and gets very, very anxious on the rare occasion that Dad is responsible for anything such as attending a concert (he has attended 2 over 3 years)
I do not ever share my ex-husband's negativities with my DC but I can see all of the very valid points that come out of my 11 year olds mouth and I have very little constructive feedback, other than 'your Dad loves you and is just different' because what is being said is correct. My DC's self worth has corroded because the message that has come through loud and clear is 'Dad thinks I am not worth making the effort for'.
You have no guarantee that making changes to the amount you see your children will help in any way shape or form.
What I can guarantee is it will impact your relationship with your children negatively and regardless of how understanding you say they are, they will get the message that Dad took an option that basically meant less time with us and more time with his girlfriend and friends and that will never end well.
I think you should get some help for yourself as an individual. I don't think any of your decisions should be based on your new partner, job or friends. The only way to do this 'guilt free' is to know hand on your heart that you are doing it for the right reasons and the only 2 factors that should matter are your children and the impact on their mum and your own personal health. Everything else should be secondary.
You need to work out what your capabilities are and be honest with all parties about them.
If you cannot talk to your ex-partner about this issue then suggest Mediation or family counselling to find a way. Like it or not, you are bound together as a family for life because you had children together.
