Oh, i feel like somewhat of an expert on this being that i went through this three weeks ago (and counting)..... My brother and I have been very close because of our family situation and its been hard dealing with the fact that even though we both love each other and i am very close with my new sister-in-law things are different but Jehovah has really helped me through the rough times
It's nice that you were able to adjust. When we first got married, my husband's brother was around far too much - and he'd been married for 3 years at that point. I'm sure your sister-in-law appreciates your attitude.
