For example, I come from a religious family but he is not although he admits he needs to sort this out, this also creates tension.
Why does he need to sort this out? Surely his religious or spiritual beliefs, or lack thereof, are completely down to him, @Cappucino777? You married the man, not the image of what he could be, if you just forced him to make some changes here or there. If you want to be religiously observant, amazing. If you want to raise your child to be, all power to you. But let him do him.
My mum is from the south of Holland, deeply Catholic area. Her mum was all in on the church, super devout. Her dad refused to go, whether for confession, Sunday Mass or any of the observances. They were happily married for sixty years, and their kids are mixed, some religious and some not. They all had to go until they were adults, when they could make their own choice.
The more posts I see from you, OP, the more I feel for your poor husband. You talk to your controlling parents three times a day, who make your lives hell, insult your husband and have made you feel conflicted and unworthy since you had your son.
GET IT THROUGH YOUR HEAD. You are a family unit now. You, your husband, your kid. Stop being a daughter above all else, and be a wife and a mother. You three are your priority now, and others come after.
Or you’ll be back living at home within the next three years, alone with your child and looking after your parents until they die, having them control what you wear, what you eat, what you think and how you live. Never having had a life or personality of your own - just a living extension of them.
Snap the fuck out of it.
