help! would this bother you?!

if your husband has an event going on every month and you have a 1 year old and are pregnant so it's hard for you to help him so he gets one of your friends to help out and eventually help him full time, let me add she is very attractive and of course I look like a whale and am very self conscious from my previous pregnancy. and everyone at the event thinks or assumed she is your husband's wife because she is with him the whole time talking to people while I am so busy chasing around our toddler.

would this bother you? I feel like I'm nothing , this is really bothering me and I feel like no matter what I just have to suck it up because of course I don't want my husband to stop this event because of me, and I get it she's my friend but I'm just having a hard time and need advice.

update: I have talked to him multiple times about it, since the beginning I told him it was a bad idea and I didn't like it, but he needs the help and she's the only one we know that is willing to learn and help.

not sure if it's my hormones but I have not stopped crying since it crossed my mind to ask him if people thought she was his wife and he hesitantly told me yes, it hurts my feelings and I feel like he isn't open with me about a lot . in my opinion I think he needs to be more professional and not so friendly but that's just the way he is and I am having a hard time with it, idk what to do. I stormed out of the room and have not talked to him since he admitted that to me. idk if I'm being crazy please let me know what you would do in my shoes
