Is it normal to work 7-days a week?

The answer to this is so obvious, how are you seriously asking this question?

I love your work ethic i wish i could have one like yours im a bit jealous. but you should work to pay off any loans and debts you have then chill back on the jobs a bit. Your in a relationship you have to put work into that if you really care and want it to go somewhere. dont forget whats important to you dont work yourself into an early grave or work so much you end up alone because you dont have time for anything else.

You're a way better man then I am.

your marriage, relationship, friendship, health, everything will be suffered, u'll be messed up, and will be stuck in many difficulties

It's quite common to work between 60 and 80 hours a week when working as a tradesman, in fact I usually go for those kinds of jobs short term(2-3 months). I couldn't imagine doing it long term though.

I don't recommend it. It'll be fine until there's a crisis in one area of your life, and then you don't have any time to recuperate or fix the problem. I crashed my car three times in one year when I tried working like a robot. The crisis started when there was friction between me and the boss, in retrospect mostly because I didn't have much patience due to lack of leisure time

Its your life, so if you honestly enjoy working that much, then by all means work more than the average. However, I do think you should take at least one day off because you'll either overwork yourself or become a workaholic. You need to learn to manage time and money realistically, and give yourself breaks. In the long run it will be more healthy.

Do what you have to do while you are young enough and have the energy to do it. However, long term your relationship will suffer so tighten your belt and spend less.

I disagree with loans for luxury items / holidays and live by - "If you can't afford it, you don't need it."

Dude you'd be living to work.
