Often some people will prioritize their siblings more than their spouse. The siblings might have a family of their own, yet your spouse will prioritize them over you.
Maybe this happens more in arranged marriages than love marriages.
I don’t have a good or definite answer. Keeping in mind the whole 360 degree perspective that I have experienced. There are some good reasons to want to pull back one’s spouse from his/her parental family and there are bad reasons.
To keep it short, I’ll summarize good reasons to be those that if a spouse is not pulled back from his/her parental family it would lead to divorce, financial hardship, physical harm or serious legal troubles. For example, pulling back your spouse who is being coaxed into becoming a guarantor of a big loan for a sibling, whom you believe may not be able to return it is a good reason.
Bad reasons would be every reason which is not a “good reason” as described above. For example, pulling back a spouse from the parental family because the couple is being required to make some lifestyle changes is a bad reason.
If you are a good man and secure than you would support your spouse in whatever makes her happy. A spouse cannot demand or force love. He has to earn it.
Say’s who, a good man who’s been legally loyal to a single woman?
Or are you suggesting earn love by letting go of their siblings?
There were certain boundaries needed to be set here before indulging into the drama that marriage itself brings in, as in where you’ve mutually agreed to be taking care of their/your siblings fully knowing they will be needing your help for whatever reason (s), and without anyone ever tryna a make a drama about it..
Aaaaa
You seem to want to make a loving relationship into a business transaction
Love is not a transaction
Aaaa
Not at all uncommon in Asian countries for the son in law to be supporting their wife's family, or even vice versa in some cases. Same goes for siblings, if they're broken you try and do your best to help them back up, and for as long as you can. It's just something which is ingrained in Asian societies
It's amusing to read how you constantly correlate actual love with money. Backstory behind you living in with your brother (s) on their expense, and reasons why are they as accommodating as they are to you? Assuming they were raised right by their parents, this daughter was raised the exact same way. In fact, way better than a white boy sending his Asian wife's parents into a nyc retirement/shelter home, or for another to be raising a daughter who gets roasted either way
if you good at cookery or sexytimes, you can easily fix this.
