Jesus had boundaries... .no money lending in the temple, etc... .and enforced them in ways that we here would not approve of!
He seems to think that there is one Biblical truth, which he is more in touch with than you. (Rather than a collection of verses and stories that can be interpreted different ways, some are applicable to a situation and some are not, etc). Do you agree with him?
I'm not sure it's worth it to just go back and forth citing verses... .he's always going to be able to find verses that suggest that you're too prideful and should just suffer rather than try to change the situation. Like Lifewriter says, those verses are in the same book as the verses about wives submitting to husbands' authority. If you're going into this hoping the BC will tell wife that Jesus is on your side, so she has to accept that without questioning... .I'm not sure what you can do when BC says Jesus is on her side.
If the genders were reversed, I'm not sure female-FF would bat an eye at being told she just has to suffer and submit to biblical authority. It's a pretty common mindset among (abused) Christian wives.
I chose to stay in my r/s and suffer for the benefit of my stepdaughter. If I had thrown her mother out (when she was 15, which is when things started to go south), my stepdaughter would have had to finish her teenage years with an unstable mother. There is also a good chance that she would have gotten into all sorts of trouble because her mother was more of a "friend" to her and set very few boundaries.
Suffer, I did. In spades. But I still don't regret it because my stepdaughter had no choice in what would have happened if I threw her mother out. When I think about all of this today, it still appears to me to be that this suffering was Christian in nature; done for someone who was helpless; for someone who would have suffered in my place if I had cast off my own suffering.
Suffering for the benefit of an adult is a different story, I think. I did suffer for my ex's benefit for a while... .but, unlike her daughter, she had choices and options but continually made poor choices that caused me to suffer greatly. As autonomous adults, we each get to make choices - and there is nothing biblical about suffering for the rest of your life due to the repeatedly poor choices of another adult.
The Bible doesn't magically contain all the answers - you have wrestle with scripture, and with God in prayer.
Something sounds very "off" about the advice you're receiving.
