I do agree with most of this. I still find it hard in our marriage, but I never want to divorce. I beleive that once God has brought two persons into marriage, they can manage living together and for Him for a life time!
We have been newly married in now 5 months and some few days, and trust me, it has nothing with just discovering bad habits nor differences. We learned about those before marrying. More complicated and difficult things came up before marrying, and it is still being very Hard for me to swallow most of this, and if this is being difficult for me, then it does so for my husband too. Still I wanted to marry him, and I don't regret that. I just think the past is still difficult to handle. I am doing better now, but can have my emotional and tearfull moments. But with God, every marriage can succeed in Him, even those marriages that looks so fragile, because nothing is impossible for Our God!
Although I sure agree with you Gracia, that it is frustrating how many marriages nowadays, and especially of those that are Christians, that they are easily breaking apart these days. But, remember, with God, everything is possible, also restoring deeply broken marriages!
