Fair. Not fair.
Reasonable. Not reasonable.
I’m speaking here as a single mom who’s been divorced for over 11 years, and my son is only 14. As a teacher, I make twice as much as my ex, who is a massage therapist, so I also understand having to be the main financial support (though this has improved dramatically in recent years, thanks God!).
I have been through A LOT with my ex around our son, custody, who pays what, and so on. We have no family in town, so everything has fallen on our shoulders alone to make things work. We had an “easy” divorce – no lawyers, did all the paperwork ourselves and presented it to a judge. My heart was still ripped to shreds, my son was a broken mess when his dad moved out, and I was angrier than I knew I could be (and that’s saying something for a fiery Latina like myself).
So please hear me when I say I completely understand your frustration and anger in this situation.
Feel free to vent here to your heart’s content, if it helps you.
But whether you are right or wrong, nothing anyone here says is going to change your situation. And fighting with your children’s mom(s) is not going to change anything for the better either.
Consider the possibility that you taking on the burden of doing most of the driving will also give you time to spend with your child(ren) in the car, telling stories, telling jokes, talking about life, finding out indirectly if their needs are being taken care of (which seems to be of genuine concern).
In the end, you will have to decide your own course of action, and whether it’s better to force the issue, or whether it’s better to maintain the peace. No one can answer that for you. But do consider the tender hearts of your children in all this – even if you never say an unkind word about their mother, they will know if there’s tension between you two.
And I absolutely agree with @Viki63 – sometimes expecting the best of people can encourage them to be better.
I will keep you in my prayers.
