Bolding is mine and to that, I completely disagree. Now in this family, I understand the closeness of the Big 3, especially Kate and Kevin. However, in reality that isn’t always true. I know Toby and Kate aren’t married, but my husband comes first. The day I agreed to marry him, he became my family.
Each family dynamic is different, but thing rarely work out when outside people (yes, even family) continuously take priority. I think in this instance, Toby was real, honest and vulnerable - which was such a nice change from the passive-aggressiveness of last season.
See, I think it just depends and I totally see both sides of it. My sister's and I are very close and I get that it's not popular, but honestly in my heart, my kids come first, sister's second and then my DH. My DH is not "my person," my sister's are and honestly there's no one I trust more than them. We always joke that we need to put in writing that we want each other to be the ones deciding medical things for us if we're unable. It's not that we don't love/trust our husbands, but it's just not the same.
On the other hand I completely understand that can really suck for the other person, especially if they're not close to their family. I think Toby had every right to feel like the 3rd wheel at times, but I also think Kate and Kevin have every right to be so close and so far I don't think either have overstepped their boundaries.
Just for the record, my DH and I have been married almost 18 years, my sister and husband 8, and youngest sister and husband 2 years...so far for all it's worked. Everyone just has to be understanding and sensitive to the relationships. It's not something to feel threatened by.
