Do I have the right to feel bad/weird about this?

Jaida • 20 SO 23| trying for our first LO, want our sticky bean💛💫🐘| Engaged💕 05/7/19|Married💍03/14/20|

My SO was on the phone with his grandma the other day. He called to let her know that yesterday was my birthday and that we were going out to dinner and that she and my SOs grandfather were invited.

They talked for a bit and then he brought up that we finally had set a wedding date. They continue to talk for a bit about the wedding and my birthday and just life.

As we were getting ready to leave my fiance is trying to say bye to her (hes been on speaker phone with her this whole time walking around getting ready) so hes trying to say bye and she goes "Hey...(SOs name) are you sure you want...to get married? Like this is really want you want to do?"

And to me it seem like she was going to say "are you sure you want to marry Jaida?" But last minute changed it. So now my feelings are a little hurt.

My fiance brushed it off when I asked him about it later, and tried to assure me that his grandma and family like me. And that since I'm his first real real relationship that, that's why his grandma and other family members have asked him if he really wants to get married.

None of my family has ever asked if I really want to marry my SO. So I think it's a little weird that everyone on his side is asking him. And apparently they all have asked him within the last few weeks when we let everyone know the wedding date and everything. Like family members my SO hasn't talked to in years or that weren't really invited to the wedding.

So my question is: do I have the right to feel bad/weird about his family members asking him if he really wants to get married? I feel like a lot of them have asked him if he really wants to marry me or not but my SO didnt tell me that to spare my feelings.
